Patent number: 11970618Abstract: A vulcanizable rubber composition comprises an interpenetrating or ionic network (IPN)-promoting resin. The resin comprises side chain functional groups along the resin backbone, which, in the presence of an additive material, form the connections that make up the IPN. In one embodiment, such material is ZnO. A method for forming the rubber composition comprises, in a productive step, mixing the product of the non-productive step, the zinc oxide, and a resin derived from maleic anhydride. The zinc oxide and the resin are simultaneously added to the composition during the productive mixing stage. The rubber composition can be cured and incorporated in a tire component, such as, a tread.Type: GrantFiled: July 21, 2021Date of Patent: April 30, 2024Assignee: THE GOODYEAR TIRE & RUBBER COMPANYInventors: Paul Harry Sandstrom, Kelsey Elizabeth Cantwell, Seth Cody Ensign, Nihat Ali Isitman

Patent number: 11767388Abstract: The compatibility between silica fillers and synthetic rubbers which are synthesized utilizing lanthanide-based catalyst systems, such as neodymium catalyst systems can be improved by terminating the polymerization with a vinyl silane terminating agent. In doing so the vinyl silane is allowed to react with the polymer chain ends of the neodymium rubber to functionalize the chain ends of the polymer chains with silicon containing groups. This results in the rubber having better characteristics for utilization in tire rubber formulations, such a tire tread formulations, that exhibit improved wear characteristics and lower rolling resistance. The process for the synthesis of such functionalized polydiene rubber comprises (1) polymerizing a diene monomer in the presence of a lanthanide-based catalyst system, and (2) terminating the polymerization with a vinyl silane terminator.Type: GrantFiled: September 17, 2020Date of Patent: September 26, 2023Assignee: The Goodyear Tire & Rubber CompanyInventors: Seth Cody Ensign, Margaret Flook Vielhaber, Jena Lynn Johngrass, Liqing Ma
