Research progress in fluoroalkenes copolymerization

The development of fluoroolefin copolymer resins,and the relative researches on the copolymerization between fluoroalkenes and dry proton monomers are summarized.In most cases,random copolymers are obtained during the copolymerization of fluorinated alkenes.The types of fluorinated monomer and co-monomer are very much involved in polymerization reaction,however,finished products can mainly be divided into thermoplastic,elastomer,and thermoelatomer according to their performance and application.Some properties of fluoropolymer,such as solubility,cross-linking curability,adhesion,etc.,can be compensated by introducing some monomers with special function to the copolymerization system.In addition,the Q-e parameters of some fluorinated monomers are listed in this article.Finally,alternating copolymerization based on electron-withdrawing fluorinated monomer with electro-donating hydrogenated monomer is presented and illustrated with examples.
