摘要

The present invention relates to VDF-co- (TFE or TrFE) polymers having a molecular weight of at least about 1,000,000 g / mole and a melting temperature of less than about 240 占 폚. The VDF copolymer contains at least about 50 mole percent of VDF monomers and may contain a predetermined amount of at least one other monomer. The VDF copolymer can be used for the formation of a film having a node and a fibril structure. The membrane has a percent porosity of at least 25%. VDF copolymers, subjecting the lubricated polymer to pressure at a temperature below the melting point of the VDF copolymer to form a preform material, and expanding the preform material at a temperature below the melting temperature of the VDF copolymer To form a VDF-co- (TFE or TrFE) polymer film. Dense VDF copolymer articles, filled VDF copolymer membranes and VDF copolymer fibers are also provided.
