A method comprising the step of melt processing stabilized composition comprising a copolymer comprising from 70 to 95, and preferably 75 to 90 percent by weight of vinyl chloride and from 5 to 30 and preferably 10 to 25 percent by weight of chlorotrifuloroethylene and an effective amount of a stabilizer. The step of melt processing includes extruder processing or roll mill processing. A preferred melt processing step is melt coating the copolymer onto a substrate such as a wire. The present invention includes a substrate such as a wire melt coated with the above-described stabilized copolymer.

Method of melt processing and article made of a stabilized copolymer of

About equimolar ethylene/chlorotrifluoroethylene copolymer compositions are stabilized against thermal degradation by incorporating therein a stabilizing system comprising (a) a phosphite of an organic plyhydric phenol; (b) a salt of a carboxylic acid and a metal of Group II of the Periodic Table; and (c) an ester of a (4-hydroxy-5-alkylphenyl)alkanoic acid.

Stabilized ethylene/chlorotrifluoroethylene copolymer composition

A melt processable fluoropolymer compositon stabilized against thermal degradation by incorporating therein a stabilizing system comprising (a) a hindered phenol pentaeythritol diphosphite, and (b) a salt of a carboxylic acid and a metal of Group II of the Periodic Table.

Stabilized fluoropolymer composition

A foam composition comprising an ethylene-chlorotrifluoroethylene copolymer, a blowing agent and a nucleating agent. The nucleating agent is the carbonate or oxide of a metal cation from the group of metals consisting of magnesium, calcium, barium, zinc and lead. The invention also is a method of making the above foam copolymer composition.
