Abstract
It has been discovered that certain monofunctional thiuram compounds can be synthesized at low cost and utilized as vulcanization accelerators which provide excellent cure rates without causing a high level of scorch. The use of these monofunctional thiuram compounds as vulcanization accelerators also result in cured rubber compositions that exhibit reduced compression set, improved age hardening characteristics, and degradation resistant crosslinks. These monofunctional thiuram compounds are of the structural formula: wherein Rand Rcan be the same or different and represent organyl radicals, wherein Rand Rcontain a total of at least 8 carbon atoms, and wherein Rand Rcan join together to form a cyclic structure, and wherein Rrepresents an organyl radical containing at least 6 carbon atoms.
