Abstract: The vulcanization rate of rubber stock compounded for curing is increased by using in the stock for the cure an accelerator of certain amine-substituted esters of phosphorodithioic acid.
Abstract: A cured or uncured chlorinated polyethylene composition comprising(A) chlorinated polyethylene,(B) a complex formed between hexamethylphosphoric triamide and a member selected from the group consisting of carboxylic acids, cyanuric acid, substituted or unsubstituted phenols, alcohols and metal salts, and(C) a member selected from the group consisting of (a) a mercaptotriazine, (b) a thiuram disulfide and (c) sulfur. And a process for curing chlorinated polyethylene, which comprises heating it in the presence of (B) and (C) at a temperature of about 100.degree. to about 200.degree. C.
