Patent number: 11773238Abstract: 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 R1 and R2 can be the same or different and represent organyl radicals, wherein R1 and R2 contain a total of at least 8 carbon atoms, and wherein R1 and R2 can join together to form a cyclic structure, and wherein R3 represents an organyl radical containing at least 6 carbon atoms.Type: GrantFiled: February 19, 2021Date of Patent: October 3, 2023Assignee: THE GOODYEAR TIRE & RUBBER COMPANYInventors: Thomas Franklin Spilker, Frank J.

Patent number: 11685712Abstract: The present invention provides a route for synthesizing monofunctional thiuram compounds that is safe, environmentally friendly, and cost effective. This method specifically involves synthesizing a monofunctional thiuram by (1) reacting a tetraorganylthiuram disulfide with an organyl mercaptan to produce the monofunctional thiuram and a dithiocarbamate metal salt or a dithiocarbamate metalloid salt under basic conditions, (2) separating the monofunctional thiuram in an organic phase from the dithiocarbamate metal salt or the dithiocarbamate metalloid salt in an aqueous phase, and (3) recovering the monofunctional thiuram from the aqueous phase. The monofunctional thiuram compounds made in accordance with this invention are of particular value as accelerators for use in the vulcanization of rubber. The use of these monofunctional thiuram compounds as accelerators provides good cure rates and as well as good scorch safety.Type: GrantFiled: August 24, 2022Date of Patent: June 27, 2023Assignee: The Goodyear Tire & Rubber CompanyInventors: Thomas Franklin Spilker, Ji Yang Jin, Frank J.
