Abstract
A butadiene heteropolymer latex is prepared by emulsion polymerizing appropriate monomers in the presence of polyvinyl alcohol and a stabilizing solvent. The butadiene heteropolymer can be a butadiene copolymer or terpolymer prepared from butadiene monomers and comonomers such as .alpha.-haloacrylonitrile and acrylic acid. The butadiene heteropolymer 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 heteropolymer latices also avoid the side effect problems associated with polymers prepared utilizing conventional surfactant-based emulsion polymerization techniques.
