METHOD FOR MODIFYING CHLOROPRENE COPOLYMER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing and modifying a new modified chloroprene copolymer for producing carboxy group in a copolymer by hydrolyzing carboxylic anhydride unit in the copolymer consisting mainly of chloroprene monomer unit and an unsaturated carboxylic anhydride monomer unit. SOLUTION: This method for producing the modified chloroprene copolymer containing carboxy group is provided by hydrolyzing carboxylic anhydride unit in the copolymer consisting mainly of 2-chloro-1,3-butadiene monomer unit and the unsaturated carboxylic anhydride monomer unit.
