摘要

This invention provides 3,3,3-trifluoro-2-trifluoromethyl propene/1,1-difluoroethylene copolymers additionally containing from about 0.1 to 30 mol percent of perhalogenated monomer selected from the group consisting of tetrafluoroethylene, chlorotrifluoroethylene and mixtures thereof, and method for making them. Addition of the perhalogenated monomer reduces melting point and crystallization temperature of the copolymer, thereby improving its melt processing characteristics, without seriously deteriorating its good mechanical properties and chemical resistance.
