New fluorinated polymer products useful for the polymerization of fluorinated vinyl monomers such as e.g. tetrafluoroethylene, fluorinated vinylidene, hexafluoropropane and their copolymers

摘要

Fluorinated polymer products (I) and (II) are new. Fluorinated polymer products (I) and (II) of formulae Rf(CH2CF2)mSO2M and Rf(CH2CF2)m(CH2)naSO3M are new. Rf1-5C (preferably 2-4C) perfluoroalkyl; m : 3-6; na : 0 or 2; and M : H, alkaline metal or ammonium group or ammonium group comprising substituted lower alkyl.
