Definitions

  • Copoly ers of carbon monoxide and an olefin commonly termed a "polyketone",' are a well-recognized class of copolymers synthesized through copoly erization of carbon monoxide with one or more olefins in the presence of a suitable catalyst.
  • the present invention resides in the use of a blend of an amine compound and an epoxy compound as the stabilizing agent for the aforementioned class of polyketone.
  • such polymers will have a molecular weight of anywhere from about 1,000 to about 1,000,000, preferably about 50,000 to about 250,000. They can be formed by polymerizing the appropriate monomers (i.e. carbon monoxide and the selected olefin or olefins) in the presence of a catalytic amount of a catalyst formed from a compound of a Group VIII metal, an anion of a non- hydrohalogenic acid, and a bidentate ligand of phosphorus, arsenic or antimony.
  • the appropriate monomers i.e. carbon monoxide and the selected olefin or olefins
  • the above- referenced polymers have intimately mixed therewith a suitable stabilizing quantity of a blend of an amine compound and an epoxy compound.
  • the amine compound which can be used herein needs to have at least one amine functionality (i.e., organic compounds derived from ammonia by replacement of one or more hydrogen atoms by alkyl, aryl, etc., groups as described in greater detail below) which will not react with the polyketone, e.g., by forming a Schiff base with the polyketone.
  • Monoa ines and polyamines are contemplated for use herein. If a polyamine is chosen, the chosen polyamine needs to be one in which the multiple amine functionalities do not cause crosslinking of the polyketone.
  • Aromatic amines which can be used in accordance with the present invention may contain from one, or two, or three aromatic structures, from about 6 to about 50 carbon atoms inclusive, and at least one a ino group.
  • HN(Ar-R) 2 where Ar is selected from phenyl and naphthyl and R is hydrogen or alkyl are .'preferred.
  • Representative amines of this type include VANLUBE 848 mixed octylated diphenylamine and diphenylamine and VANLUBE 81 p,p'-dioctyldiphenylamine, both available from R.. T. Vanderbilt Company Inc. Also included is IRGANOX LQ6, an alkylated phenyl naphthylamine from Ciba-Geigy.
  • Aliphatic amines which can be used include the primary and secondary amines containing bulky hindering substituents (such as branched groups, including t-butyl) , and the tertiary amines.
  • the epoxy compound stabilizer component which can be used with the aforementioned aromatic amine compound include the type of epoxy compounds described in U.S. Patent No. 3,948,832 at Col. 2, lines 20 to 47 inclusive, which is incorporated herein by reference.
  • Representative compounds are organic compounds (e.g., aliphatic, including cycloaliphatic, or aromatic which contain one or more epoxy groups.
  • One particularly preferred epoxy is an epoxy cycloaliphatic carboxylate, such as (3' ,4'-epoxycyclohexylmethyl) 3,4- epoxycyclohexanecarboxylate.
  • both the amine and epoxy compounds chosen have a relatively low vapor pressure so that they will be retained in the po ⁇ yketone during high temperature processing or use of such compositions.
  • the amounts of the stabilizer blend that are used in accordance with the present invention can range anywhere from about 1%, by weight, up to about 25%, by weight of the polyketone. Preferable amounts range from about 5% to about 15%, by weight, of the polyketone. Generally, it is advisable to choose an amount of .stabilizer at the lower portions of the above given ranges in order to avoid adversely affecting the mechanical properties of the resulting polyketone.
  • the weight ratio of aromatic amine compound to epoxy compound in the stabilizer blend can range anywhere from about 1:5 to about 5:1.
  • the stabilizer blend of this invention is preferably added to the polyketone by blending when the polyketone is in the form of a powder or dissolved in a solvent.
  • the method of incorporation is not believed to be critical although it is preferred that a homogeneous mixture of polyketone and stabilizer blend be achieved.
  • Other additives such as fillers, extenders, plasticizers, coloring agents, other polymeric materials, etc. , can be added to the polyketone being stabilized.
  • the resulting stabilized polyketone compositions exhibit improved thermal stability and can be processed for extended periods of time at elevated temperatures with an enhanced degree of stability.
  • Typical methods of processing include injection molding, pressure forming, thermoforming and sheet extrusion.
  • the materials can be used in applications where such polyketones are likely to encounter elevated temperatures including the thermoforming of food or drink containers, the production of shaped automotive parts by injection molding, or the production of wire and cable coatings by extrusion.
  • a CO/C 2 H 4 polyketone copolymer or CO/C 2 H 4 /C 3 H 6 polyketone terpolymer was suspended in hot acetylacetone. The suspension was stirred for fifteen minutes at 120°C and was quickly filtered without cooling. The polymer was then washed with cold acetylacetone followed by washing with acetone and vacuum drying.
  • the CO/C 2 H 4 copolymer or CO/C 2 H 4 /C 3 H 6 terpolymer after catalyst residue removal was then added to an acetone solution of a modifier or modifier blend described hereinafter and was dried with constant stirring to achieve good sample uniformity. Samples were then pressed into pellets which were then placed in the preheated testing chamber of a RHEOMETRICS RMS 800 rheometer.
  • the rheometer is capable of measuring both components of complex viscosity (eta*) , namely, the real (or loss) component (eta'), which can be correlated to the contribution of the viscous behavior of the material, and the imaginary (or storage)' component (eta”) , which can be correlated to the contribution of the elastic behavior.
