STABILIZED POLY(ARYL ETHER KETONE) COMPOSITIONS Christine Ellen Vogdes Brackin Larson Andrews Poly(aryl ether ketones) are stabilized against crosslinking and thermooxidative degradation at elevated temperatures, e.g. temperatures typically used to melt process the polymer, by incorporating therein a particulate molecular sieve, for example, a crystalline aluminosilicate, such as a synthetic zeolite. The amount of molecular sieve is preferably about 0.5 to about 5% by weight based on the weight of the poly(aryl ether ketone). |
