Abstract

Described herein is a composition comprising a fluorothermoplastic polymer, wherein the fluorothermoplastic polymer is derived from: (a) 60-85 mol % tetrafluoroethene; (b) 2-12 mol % hexafluoropropene; (c) 10-30 mol % vinylidene fluoride; (d) 0.2 to 5 mol % of a bromine-containing monomer. Such compositions can be used in multilayer constructions in, for example, fuel hose applications.
