Abstract

Described herein is a composition comprising (i) a hydrofluorothermoplastic polymer, wherein the hydrofluorothermoplastic polymer is derived from: (a) 50-85 mol % tetrafluoroethene; (b) 2-15 mol % hexafluoropropene; (c) 10-35 mol % vinylidene fluoride; and (d) 0.1 to 5 mol % of a bromine-containing monomer; and (ii) a perhalogenated thermoplastic polymer. Such compositions can be used in multilayer constructions in, for example, fuel hose applications.
