<p>An improved melt-processable composition of a thermoplastic polymer selected from the class consisting of hexafluoroisobutylene/vinylidene fluoride copolymer, and ethylene/chlorotrifluoroethylene copolymer, wherein added to said thermoplastic polymer are a phosphite ester and an oxamidoester. A preferred phosphite ester is tris (2,4-di-tert-butyl phenyl) phosphite, and a preferred oxamidoester is 2,2 min -oxamidobis [ethyl 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate]. In a preferred composition, about 1 wt. % of phosphite ester and about 0.5 wt.% of oxamidoester are added to a hexafluoroisobutylene/vinylidene fluoride copolymer.</p> |
