Branched and cyclic N,N-dialkyldithiocarbamyl accelerators for the sulfur vulcanization of rubber have been found to generally perform as well as the corresponding straight chain N,N-dialkyldithiocarbamyl accelerators, but surprisingly do not produce detectable amounts of environmentally undesirable N-nitrosamines. The branched N,N-alkyldithiocarbamyl accelerators are generally represented by the formula: (see formula I) where R is a branched alkyl group, R' is an alkyl group which may or may not be branched or a cyclic alkyl group or an alkaryl or aryl group, X is another thiocarbamyl group of the same general structure, a primary alkylamino group, an alkylthio group, a 2-benzothiazyl group, or a metal ion, and n is an integer of from 1 to 6. The cyclic dithiocarbamyl accelerators of the invention are generally represented by the formula (see formula II) where X is another thiocarbamyl group of the same general structure, a primary alkylamino group, an alkylthio group, a 2-benzothiazyl group, or a metal ion, and n is an integer of from 1 to 6.
