Abstract: 1,050,001. Heat - stabilized polyamides. ALLIED CHEMICAL CORPORATION. June 16, 1964 [June 17, 1963], No. 24951/64. Heading C3R. Polyamides are heat-stabilized by the incorporation of copper or a copper compound and a stannous salt. Specified polyamides are polycaproamide, polyundecanoamide, polyhexamethylene adipamide and sebacamide and polym- and p-xylylene apdiamides. In the examples various copper and stannous salts are incorporated in caprolactam during its polymerization.
