Melt Processible Semicrystalline Fluoropolymer having Repeating Units Arising from Tetrafluoroethylene, Hexafluoropropylene, and Hydrocarbon Monomer Having a Carboxyl Group and a Polymerizable Carbon-Carbon Double Bond and Multi-Layer Articles Comprising a Layer of the Melt Processible Semicrystalline Fluoropolymer |
摘要 |
Disclosed is a melt processible semicrystalline fluoropolymer comprising: (a) about 2 to about 20 weight percent of repeating units arising from hexafluoropropylene; (b) about 0.001 to about 1 weight percent of repeating units arising from a hydrocarbon monomer having a carboxyl group and a polymerizable carbon-carbon double bond; and (c) the remaining weight percent of repeating units arising from tetrafluoroethylene. This melt processible semicrystalline fluoropolymer is impermeable to fuels and is useful as a lining for petroleum fuel tubing, as well as chemical resistance coating for, or adhesive between, perfluoropolymer and other polymers, metals and inorganics.
