Patent number: 9550839Abstract: The present invention achieves increased filler interaction by incorporating a small amount (a few units per chain of rubbery polymer) of a conjugated triene monomer, such as alloocimene, randomly throughout the polymer chain of a rubbery polymer or at the chain ends of the rubbery polymer. The incorporation of the conjugated triene monomer leads to the formation of a polymer containing highly reactive conjugated diene units. These conjugated diene units can chemically react with carbon black leading to superior reinforcement. Alternatively, these conjugated diene units can be used for functionalization of the polymer with silica interactive/reactive groups using Diels Alder reactions. This functionalization of the rubbery polymer can conveniently be conducted in a mixer, such as a Banbury mixer, a mill mixer, or the like.Type: GrantFiled: July 13, 2015Date of Patent: January 24, 2017Assignee: The Goodyear Tire & Rubber CompanyInventors: Gabor Kaszas, Stephan Rodewald, Joseph John Kulig
