Abstract:
1. A polychloroprene latex comprising a homopolymer of chloroprene or a copolymer of a chloroprene monomer with a monomer copolymerizable with chloroprene, wherein the chloroprene homopolymer or copolymer is one obtained by emulsion polymerization in the presence of from 0.5 to 15 parts by mass of a nonionic emulsifier having the formula (1) and from 0.05 to 2 parts by mass of an anionic emulsifier having the formula (2), per 100 parts by mass of the whole monomer: wherein R is a substituent containing at least one benzene ring and/or naphthalene ring, n is from 1 to 200, and R wherein R is a substituent containing at least one benzene ring and/or naphthalene ring, n is from 1 to 200, R
