WATER-DISPERSIVE TYPE FLUORINE-CONTAINING COPOLYMER COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a water-dispersive type fluorine-containing copolymer composition excellent in emulsification stability of the composition and in permeation to fiber at processing of the fiber, especially capable of giving excellent oil repellency to cotton and cotton blend. SOLUTION: This water-dispersive type copolymer composition comprises emulsifying and dispersing a copolymer composed of a polyfluoroalkyl group- containing polymerizable monomer (A) and a polymerizable monomer (B) not containing a fluorine atom in the presence of an emulsifier containing a fluorine- containing anion surfactant (C).
