Fluoropolymer having S-sulfate group and water/oil repellent composition containing the polymer

摘要

A fluoropolymer comprising: (A) repeating unit derived from an S-sulfate monomer having an —S—SO₃— group and carbon to carbon double bond; and (B) repeating unit derived from a fluoromonomer having a fluorine atom and carbon to carbon double bond. This fluoropolymer can be a constituent of water/oil repellent agent having excellent water/oil repelling capability, and is stable in air and permits an arbitrary control of crosslinking.
