Abstract
A composition comprising a halopolymer, such as an ethylene/chlorotrifluoroethylene copolymer, an effective stabilizing amount of an ionomer, and an effective stabilizing amount of a compound such as a phosphite of an organic polyhydric phenol; a thioester; a phosphite; or a hindered phenolic antioxidant. Preferred ionomers are metal salts of ethylene-acrylic acid copolymers, and metal salts of sulfonated polystyrenes. The stabilized halopolymers have improved resistance to thermal degradation and suffer less discoloration when subjected to high melt processing or extrusion molding temperatures.
