METHOD FOR PRODUCING CHLOROPRENE-BASED POLYMER, POLYCHLOROPRENE LATEX, AND ADHESIVE COMPOSITION

摘要

Provided is a polychloroprene latex extremely superior in adhesion properties. According to the present invention, chloroprene or a mixture of chloroprene and a monomer copolymerizable with chloroprene is polymerized in the presence of a surfactant in an aqueous medium, in which the surfactant's concentration is lower than its critical micelle concentration (CMC) to obtain a polychloroprene latex. The polychloroprene latex produced according to the present invention is extremely superior in adhesion properties and others and give a smaller amount of deposits during production.
