<p>Chloroprene/sulfur copolymers peptized either by xanthogen sulfides alone or in combination with mercaptobenzothiazole in an alkaline dispersion are cured in the presence of N-cyclohexyl-2-benzothiazyl-sulfenamide or mercaptobenzothiazole disulfide as an accelerator and in the absence of nitrosamine forming additives. Metal oxides are the usual curing agents.</p> |
