DICHLOROAMINO-FUNCTIONALIZED FLUOROPOLYMER AND PROCESS FOR PREPARING

摘要

This invention pertains to a novel fluoropolymer characterized by a dichloroamino-functionalized perfluoroether pendant group that terminates in —CF2NCl2. The polymer so formed is crosslinkable and useful for the preparation of shaped articles and photo-imaged coatings. The novel fluoropolymer can be thermally treated to form crosslinked fluoropolymers with highly stable perfluoroalkylene crosslinks. The novel fluoropolymer is conveniently prepared by treating a cyano-functionalized fluoropolymer with Cl—F.
