ABSTRACT:
A method for, and compositions, providing vulcanizable compounds of unsaturated polymers having an improved balance of scorch time and cure rates, ie., slow scorch times and fast cure rates, comprising adding to said vulcanizable polymers accelerating amounts of benzothiazolesulfenamides selected from the group consisting of N-oxydiethylene-2-benzothiazole sulfenamide, N-t-butyl-2-benzothiazole sulfenamide and N-cyclohexyl-2-benzothiazole sulfenamide, with N-oxydiethylenethiocarbamyl-N'-t-alkyl sulfenamides wherein the alkyl radicals contain 4 to 8 carbon atoms.
