Summary:Process for producing a cationic polychloroprene latex by homo- or copolymerizing chloroprene in an aqueous emulsion in the presence of ammonium salts of inorganic or organic acids as emulsifiers wherein the copolymerization is carried out in presence of an alkaline earth and/or alkali salt of an organic carboxylic acid or in presence of a mixture of: Na2HP04 and XH2P04. The latex thus obtained may be mixed with a bitumen emulsion and can be used for the protection of building or in road construction.
