Abstract
Polychloroprene latexes, well suited for the production of adhesives, are prepared by (co)polymerizing chloroprene, in aqueous emulsion, in the presence of a free-radical initiator and at least one emulsifying agent, said aqueous emulsion further comprising (a) at least one non-carboxylic ionic surfactant and (b) at least two nonionic surfactants, the HLB values thereof differing by at least 3 units.
