Low-melting tetrafluoroethylene copolymer and its uses

摘要

Copolymers of tetrafluoroethylene (TFE) and hexafluoropropylene (HFP) having high HFP content and end-of-melting temperature, Tm(end), as low as 200 DEG C. are disclosed. These copolymers contain one or more additional fluoromonomers such as perfluoro(alkyl vinyl)ether. These TFE/HFP copolymers are soluble in fluorinated cyclic solvents.
