DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1.

2. Description of the Related Art Polyphenylene ether resins are resins having excellent properties such as excellent heat resistance, electrical properties, acid resistance and alkali resistance, and low specific gravity and low water absorption. 2. Description of the Related Art In recent years, a reinforced resin composition material containing an inorganic filler has been used as a core material of a coil bobbin of an electric component, taking advantage of electric characteristics and high heat resistance. In the above applications, the reinforced polyphenylene ether-based resin composition is often used in various colors for discrimination.

However, when a core material of a coil bobbin is obtained by using this coloring material, crazes and cracks are generated in the core material made of the coloring material due to a curing agent used for curing an epoxy resin forming around the core material. However, in severe cases, the core material was sometimes destroyed. JP-A-60-
JP-A-233150 discloses a composition in which a glass fiber and zinc sulfide are blended with a polyethylene terephthalate-based resin, and discloses that the composition is excellent in heat resistance and mechanical properties as compared with a composition colored with titanium oxide. JP-A-6-1
No. 92563 discloses a composition excellent in moldability, rigidity and dimensional stability in which an inorganic filler is blended with a polyphenylene ether resin, and further specifies the use of an ignition coil bobbin. However, in these publications, other documents, etc., there was no report examining the resistance of the epoxy curing agent when embedding the reinforced polyphenylene ether-based resin composition with the epoxy resin, and the resistance to the epoxy curing agent was not observed. The invention of an excellent reinforced resin composition and a reinforced polyphenylene ether resin composition has not been achieved.

[0004]

Among them, poly (2,6-dimethyl-1,1)
4-Phenylene) ether is particularly preferred. The polyphenylene ether copolymer is a copolymer having a phenylene ether structure as a main unit. For example,
Copolymer of 2,6-dimethylphenol and 2,3,6-trimethylphenol, copolymer of 2,6-dimethylphenol and o-cresol, or 2,6-dimethylphenol and 2,3,6- Examples include a copolymer with trimethylphenol and o-cresol.

The method for producing the homopolymer or copolymer of the polyphenylene ether resin used in the present invention is not particularly limited. For example, US Pat. No. 4,788,2.
According to the method described in Japanese Patent Application No. 77 (Japanese Patent Application No. 62-77570), in the presence of dibutylamine,
It can be produced by oxidative coupling polymerization of 2,6-xylenol. The molecular weight and the molecular weight distribution are not particularly limited as long as the requirements of the present invention are satisfied.
Those having 0.7 dl / g are preferably used. 0.3d
When the reduced viscosity is less than 1 / g, the thermal stability tends to deteriorate, and when the reduced viscosity exceeds 0.7 dl / g, the moldability tends to be impaired.

In the polyphenylene ether resin of the present invention, various other phenylene ether units which have been proposed to be allowed to exist in the polyphenylene ether resin so far as they do not contradict the gist of the present invention are partially incorporated. It may be included as a structure. Japanese Patent Application No. 63-12 / 1988 discloses an example of the proposal for coexistence in a small amount.

The reaction between an α, β unsaturated carboxylic acid such as maleic anhydride or an anhydride thereof and a polyphenylene ether resin is carried out by mixing the two in the presence or absence of an organic peroxide to form a glass of a polyphenylene ether polymer. It can be produced by heating to a temperature above the transition temperature. When producing the reinforced polyphenylene ether-based resin composition of the present invention, a polyphenylene ether resin in which an α, β unsaturated carboxylic acid such as maleic anhydride or an anhydride thereof is bonded in advance may be used, or a reinforced polyphenylene ether may be used. A method may be used in which an α, β unsaturated carboxylic acid such as maleic anhydride or the like or an anhydride thereof is added at the same time as the production of the resin composition to react with the polyphenylene ether polymer.

Further, the polyphenylene ether-based resin may include a polyphenylene ether-based resin modified with an ethylenically unsaturated compound. In the present invention, when a large amount of an inorganic filler is contained, molding processability tends to be deteriorated.However, the polyphenylene ether resin or the reinforced resin composition modified with the ethylenically unsaturated compound is used during molding flow and molding process. It is more preferable to use it because it is excellent in suppressing discoloration.

Although not limited thereto, it is most preferable to use stearyl acrylate and / or styrene.

The ethylenically unsaturated compound is blended in a proportion of 0.1 to 15% by weight, more preferably 0.5 to 10% by weight, based on 100% by weight of the polyphenylene ether resin. If the amount is less than 0.1% by weight, the effects such as molding fluidity and coloring properties are reduced. The reaction between an ethylenically unsaturated compound such as stearyl acrylate and a polyphenylene ether resin is performed by mixing both in the presence or absence of an organic peroxide and heating the mixture to a temperature equal to or higher than the glass transition temperature of the polyphenylene ether polymer. Can be manufactured by

In producing the reinforced resin composition of the present invention, a polyphenylene ether resin to which an ethylenically unsaturated compound has been previously bound may be used, or simultaneously with the production of the reinforced resin composition, such as stearyl acrylate. The reaction may be carried out by adding an ethylenically unsaturated compound of the formula (1) to react with the polyphenylene ether polymer. Further, the polyphenylene ether-based resin as the component (A) may include a mixture of a polystyrene-based resin. The polystyrene resin is represented by the general formula (c)
