Description

TECHNICAL FIELD [0001] The present invention relates to an additive for improving processability, dispersibility and chemical resistance of a polymer resin, and a polymer resin composition containing the same. [0002]

The present invention relates to an additive for improving the performance of a polymer resin and a polymer resin composition containing the same, and more particularly, to an additive for improving the processability, dispersibility and chemical resistance of a polymer resin, And a polymeric resin composition containing the same.

In general, various additives can be used in polymer resins such as synthetic resin and rubber in order to facilitate the processing of the polymer resin and to improve the performance of the final product.

Examples of such additives include plasticizers, heat stabilizers, antioxidants, ultraviolet stabilizers, flame retardants, antistatic agents, lubricants, impact modifiers, and the like. By using such additives for polymer resins, it is possible to improve the quality of plastics, improve workability of molded products, improve physical properties, and maintain long-term stability.

For example, heat stabilizers, plasticizers, lubricants and the like are used for the purpose of improving the processability and physical properties of plastics. Antioxidants and ultraviolet stabilizers are used for the purpose of improving weatherability and durability of molded articles. The antistatic agent and the lubricant are also used for the purpose of improving the interfacial property, and the flame retardant is used for the purpose of giving special functions such as fire resistance and heat resistance improvement.

PC, PC / ABS, SAN, ABS, PPE, POM, MPPO, HIPS, PS, PVC, etc., which are insufficient in chemical resistance and are unstable due to unstable properties of polymer during processing, In the case of PES, PSU, etc., various additives can be used to supplement them.

 In recent years, these additives have been recognized as special materials that can have a decisive influence on the final performance of the plastic products beyond the original auxiliary materials. In the polymer industry, the use of additive technology in the development of new products is becoming increasingly important.

Generally, the polymer resin may be used including a filler rather than a polymer resin alone. As the filler, carbon black such as carbon black, graphite, carbon fiber and the like can be used. As the inorganic filler, calcium carbonate, mica, talc, silica, alumina, glass fiber and the like can be used and these fillers can smoothly interact with the polymer resin It is preferable that the dispersibility with the polymer can be kept high by using an appropriate additive.

Further, in the case of a polymer resin having a high processing temperature and a low melt flowability, for example, an amorphous resin such as polycarbonate, an additive capable of improving fluidity without deteriorating the inherent characteristics of the polymer resin is used to facilitate the processability of the polymer resin In the case of the present invention.

As a conventional technique relating to the additive capable of improving the fluidity of such a polymer resin, Japanese Laid-Open Patent Publication No. 10-1192949 (Oct. 18, 2012) includes a monomer unit of an aromatic vinyl monomer and a (meth) acrylic acid ester monomer unit having an ester group as a phenyl group And JP-A 2003-165842 (Jun. 10, 2003) discloses a film having hydrophilicity imparted to the surface of a polymer resin and having excellent surface activity such as anti-fogging property and anti- A plastic additive comprising a copolymer having a polyalkylene oxide chain (A) and a hydrophobic aggregate chain (B) is disclosed as an additive for enabling the production of molded articles and the like.

On the other hand, in the case of the additive used in the polymer resin, when a single additive is added, various performances can be realized, which can greatly improve productivity and cost reduction by simplifying the process.

Particularly, by using a single kind of additive, it is possible to improve the compatibility and dispersibility between different kinds of plastics, or between polymers of different plastics and rubber, or plastics and fillers, There is a continuing need to develop an additive capable of improving the processability by imparting slip property to an apparatus and improving ESCR characteristics such as chemical resistance.

The polyalkylene oxide may be obtained by polymerizing a repeating unit in which an oxygen atom is connected to the alkylene group. In this case, the degree of polymerization of the repeating unit may be 1 to 500, preferably 5 to 300. [

When the degree of polymerization of the repeating unit of the polyalkylene oxide which is the hydrophilic substituent is larger than 300, it is converted into a polymer, so that the compatibility with the plastic or the rubber and the fluidity are poor, so that it is preferable to have the above range.

Also, the polyalkylene oxide group may include at least one of hydrogen, an alkyl group having 1 to 30 carbon atoms, an aryl group having 6 to 24 carbon atoms, an aralkyl group having 7 to 30 carbon atoms, an alkyl group having 1 to 30 carbon atoms or an aryl group having 6 to 24 carbon atoms Lt; RTI ID = 0.0 &gt; R, &lt; / RTI &gt;

More specifically, the additive of the present invention can be represented by the following formula (1).

[Chemical Formula 1]

Wherein Ar is the substituted or unsubstituted aryl group; Or a substituted or unsubstituted heteroaryl group,

X1 is a single bond, any one selected from O, S and NR,

Wherein R and Y1 are the same or different and are independently selected from the group consisting of hydrogen, an alkyl group having 1 to 30 carbon atoms, an aryl group having 6 to 24 carbon atoms, an aralkyl group having 7 to 30 carbon atoms, an alkyl having 1 to 30 carbon atoms, Gt; is a substituent selected from the group consisting of &lt; RTI ID = 0.0 &gt;

Each of R 1 to R 6 is the same or different from each other and is selected from the group consisting of hydrogen and an alkyl group having 1 to 6 carbon atoms,

m and n are each an integer of 0 to 4, and when m is 2 or more, each of R 3 is the same or different, and when n is 2 or more, each R 6 is the same or different,

That is, in the structure of the additive, the substituent Ar corresponds to a hydrophobic substituent, and X1 represents a linker, oxygen, sulfur, or a nitrogen atom having a substituent, and may optionally be a single bond. Also, in the formula (1), the substituent bonded to the right of the linking group X1 corresponds to a polyalkylene oxide group which is a hydrophilic substituent group.

In one embodiment, the polyalkylene oxide group of the present invention may have two different repeating units in the polyalkylene oxide group.

That is, when p and q in formula (1) are not 0 at the same time, the polyalkylene oxide group as the hydrophilic substituent group is a polyalkylene oxide group having a substituent group of R1 to R3 and a polyalkylene oxide group having a substituent group of R4 to R6 And a copolymer of an alkylene oxide group.

For example, the polyalkylene oxide group may be composed of a copolymer of polyethylene oxide and polypropylene oxide, or a copolymer of polyethylene oxide and polybutylene oxide.

In this case, the sum (p + q) of the degree of polymerization of each polyalkylene oxide group in the copolymer may be in the range of 5 to 300.

The additives for improving the dispersibility, fluidity and durability of the polymer resin in the present invention may have a number average molecular weight of 300 to 30000, preferably 500 to 10000.

When the number-average molecular weight is less than 300, the oligomer can be discharged from the polymer resin and can not be mixed with the polymer. When the molecular weight is more than 30,000, the additive becomes excessively polymerized, The compatibility and fluidity become poor.

In the additive of the present invention, at least one of the substituents of R1, R2, R4 and R5 in Formula 1 may be an alkyl group having 1 to 6 carbon atoms. Preferably, at least one of the substituents of R1, R2, R4 and R5 may be a methyl or ethyl group.

When at least one of the substituents of R 1, R 2, R 4 and R 5 is an alkyl group having 1 to 6 carbon atoms, the alkyl group having 1 to 6 carbon atoms is substituted for the alkylene group as the main chain of the polyalkylene oxide, Can be appropriately adjusted.

As described above, by controlling the degree of polarity of the hydrophilic substituent moiety in the additive of the present invention, when the additive is included in the non-polar polymer resin, the fluidity of the polymer resin and the dispersibility with the filler and the like can be further improved, The releasability can be increased.

In the present invention, the hydrophobic substituent group containing an aryl group or a heteroaryl group may have two or more aromatic rings. Preferably, the hydrophobic substituent group may comprise a condensed aryl group having 2 to 4 rings, or a condensed heteroaryl group having 2 to 4 rings.

Illustratively, the hydrophobic substituent may be a naphthyl group, an anthracenyl group, a phenanthranyl group or the like as an aryl group, and a carbazole group, a quinoline group, or the like may be possible as a heteroaryl group.

If two or more aromatic rings are present in the hydrophobic substituent moiety in the additive as described above, the compatibility between the polymer resin and the carbon-based filler can be improved. Particularly, carbon black, carbon nanotubes, graphite and the like have a surface structure composed of aromatic components and can exhibit further improved effects.

In this case, as mentioned above, each of the aryl group and the heteroaryl group is an alkyl group having 1 to 30 carbon atoms, an aryl group having 6 to 24 carbon atoms, an aralkyl group having 7 to 30 carbon atoms, an alkyl having 1 to 30 carbon atoms, And a silyl group containing an aryl group having 1 to 24 carbon atoms.

Meanwhile, the additive of the present invention may be contained in an amount of 0.01 to 15 parts by weight, more preferably 0.02 to 10 parts by weight, based on 100 parts by weight of the polymer resin.

When the additive of the present invention is contained in an amount less than 0.01 parts by weight, it is difficult to exhibit the effect of the additive. When the additive is more than 15 parts by weight, the additive is economically disadvantageous. Can be reduced.

The method for producing the additive of the present invention can be easily produced by reacting an alkylene oxide with a compound having a reactive group such as a hydroxyl group, an amine group, or a thiol group bonded to a moiety constituting the hydrophobic substituent.

Also, by controlling the kinds of alkyl groups, aryl groups and the like as substituents which can be bonded in the substituent Ar of Formula 1, the compatibility can be changed depending on the type of the polymer.

For example, in the case of a polymer resin containing an aromatic compound, the compatibility is enhanced by introducing an additional aromatic compound as a substituent to the Ar and controlling the content thereof, and in the case of a polymer resin comprising an aliphatic compound, the Ar may be substituted with an alkyl group, a cycloalkyl group , Or a silyl group may be introduced and the content thereof may be controlled to increase the compatibility with the polymer resin.

In the present invention, the polymer resin that can be used with the additive may be any one selected from a thermoplastic resin, a thermosetting resin, a silicone resin, a fluororesin, and a rubber, or a mixture thereof.
