STABLE BUTADIENE POLYMER LATEX

摘要

A butadiene polymer latex is prepared by emulsion polymerizing appropriate monomers in the presence of polyvinyl alcohol and a stabilizing solvent. The butadiene polymer can be a butadiene homopolymer, copolymer or terpolymer prepared from butadiene monomers and optional comonomers such as alpha -haloacrylonitrile and acrylic acid. The butadiene polymer latices can be prepared without problems of coagulation and can be utilized effectively in adhesive compositions without the use of volatile solvents. Adhesive bonds prepared from the butadiene polymer latices also avoid the side effect problems associated with polymers prepared utilizing conventional surfactant-based emulsion polymerization techniques.
