Layer of melt-processible semicrystalline fluoropolymer and semi-crystalline fluoropolymer melt processable having repeating units arising from a hydrocarbon monomer having a carbon-carbon double bond polymerizable tetrafluoroethylene, hexafluoropropylene, and a carboxyl group multilayer articles, including

摘要

Disclosed are about 2 to about 20 weight percent carbon and a polymerizable (b) a carboxyl group and a repeating unit resulting from (a) hexafluoropropylene - repeating units arising from a hydrocarbon monomer having a carbon double bond a melt processible semicrystalline fluoropolymer comprising by weight percent of the repeating units resulting from (c) tetrafluoroethylene and about 1 weight percent, and about 0.001. This melt-processable semi-crystalline fluoropolymer is a fuel impermeable, as the lining of oil fuel pipe, as well as other polymers and fluoropolymers, is useful as an adhesive or chemical resistance coating between the metal and minerals.
