A process is described for the polymerization of chloroprene or of a mixture of chloroprene and a copolymerizable monomer up to 20% by weight, in aqueous emulsion in the presence of radical initiators, at a temperature between 5degreC and 70degreC, characterized in which is carried out in the presence of one or more copolymerizable surfactants in accordance with the formula described below (I) R3 -Z-CO-C (R1) = C (R2) -COOM or: R3 is a hydrocarbon chain , aliphatic or aromatic, saturated or unsaturated, linear or branched, Cn, with n from 10 to 20; R1 and R2, equal or different, are chosen from H, C1 -C3 alkyl radical; Z is selected from -O- and-NH-; M is chosen from alkali metals or NH4. |
