A tetrafluoroethylene/hexafluoropropylene copolymer with high drawability is provided. Also provided is a process employing the polymer and an article coated with the polymer.

Tetrafluoroethylene/hexafluoropropylene copolymers with higher drawability

The present invention provides a method of making a fluoropolymer comprising repeating units derived from one or more gaseous fluorinated monomers. The method comprises an aqueous emulsion polymerization of gaseous fluorinated monomers in the presence of an ether selected from the group consisting of dimethyl ether (DME), methyl tertiary butyl ether (MTBE) and mixtures thereof.

Aqueous emulsion polymerization in the presence of ethers as chain transfer agents to produce fluoropolymers

The present invention relates to a method of foaming a polymer comprising the steps of providing a composition comprising said polymer and a zeolite in an amount of 0.3% or more based on the weight of said polymer and extruding said composition. The invention further relates to foamed articles and to the use of zeolites as foaming agents in the foaming of polymers.
