Fluoropolymer Having ?-sulfate Group and Water/Oil Repellent Composition Containing the Polymer

摘要

The present invention (A) -S-SO ₃ - group and carbon-repeat derived from S- sulfate monomer unit having a carbon-carbon double bond, and (B) a fluorine atom, or a carbon - from a fluorine-containing monomer having carbon-carbon double bond having a repeating unit derived relates to a fluorine-containing polymer. The fluorine-containing polymer is a component of the water- and oil-repellent composition having excellent water repellency and oil repellency, and stable in air, it is possible to arbitrarily control the crosslinking. ; The fluorine-containing polymer, a water- and oil-repellent, S- sulfate group
