Abstract
Provided is a polychloroprene latex extremely favorable in adhesive properties.The present invention relates to a method of producing a polychloroprene latex, comprising polymerizing chloroprene or a mixture of chloroprene and a monomer copolymerizable with chloroprene in an aqueous medium containing a surfactant at a concentration of lower than its critical micelle concentration (CMC) and a polymer dispersant of a metal salt of aromatic sulfonic acid formalin condensate added thereto. The polymer dispersant for use is preferably a metal salt of aromatic sulfonic acid formalin condensate. The polychloroprene latex obtained can be used as an adhesive.
