Abstract
A nonionic polychloroprene latex composition employing a polyvinyl alcohol as an emulsifier/dispersant has favorable chemical and mechanical stability but has a high viscosity, and therefore it has such drawbacks that its coating method is limited, and it is hardly made to have a high solid content. A polychloroprene latex composition which has a low viscosity and which can be made to have a high solid content, can be obtained by emulsion polymerization of chloroprene alone or chloroprene and a monomer copolymerizable with chloroprene in the presence of a polyvinyl alcohol and a nonionic emulsifier.
