Abstract
This invention relates to copolymer compositions of poly(vinylidene fluoride-2,3,3,3-tetrafluoropropene) copolymers. The copolymers formed have excellent optical properties, corrosion resistance and electrical properties, with very low haze. Tetrafluoropropene monomer units may be present at from 0.5 to 60 weight percent of the copolymer.
