Fluorine-containing polymer

摘要

The invention provides a methylene group-containing fluoropolymer which is selected from the group consisting of vinylidene fluoride-based copolymer (I), tetrafluoroethylene-propylene-based copolymer (II) and hexafluoropropylene-ethylene-based copolymer (III),
wherein each of both main chain termini is an Si-H group, and
the number average molecular weight of said methylene group-containing fluoropolymer is 500 to 500000.
