Polymerizing chloroprene in an alkaline-aqueous emulsion in the presence of elemental sulfur to form a chloroprene polymer latex and incorporating into the system at a time no later than when the polymer is in the latex state, e.g., during polymerization, at least about 0.5 part by weight per hundred parts organic monomer of a sulfenamide compound having the structure WHERE R and R'' are alkyl, cycloalkyl, aralkyl radicals or one of R or R'' can be hydrogen, or R and R'' together can form a saturated ring with the nitrogen, e.g., 2(morpholinothio)benzothiazole and after polymerization and subsequent to the addition of the sulfenamide, or at the same time the sulfenamide is added, separately adding certain peptizing agents. |
