POLYCHLOROPRENE LATEX COMPOSITION AND PROCESS FOR PRODUCING THE SAME

摘要

Nonionic-type polychloroprene latex compositions containing a polyvinyl alcohol as an emulsifier/dispersant have had problems, e.g., that they have a high viscosity and techniques for application thereof are hence limited and that it is difficult to prepare the compositions so as to have a high solid content, although satisfactory in chemical and mechanical stability. A polychloroprene latex composition capable of having a low viscosity and a high solid content is obtained by emulsion- polymerizing either chloroprene alone or chloroprene and a monomer copolymerizable with chloroprene in the presence of polyvinyl alcohol and a nonionic emulsifier.
