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).
