摘要：
A composition includes a vulcanizable diene rubber, a silica filler, and a metal-functionalized polyisobutylene succinic anhydride derivative. In one embodiment the composition has a reduced amount of oil and may include no oil. A tire tread composition includes, a silica filler, a metal-functionalized polyisobutylene succinic anhydride derivative, a rubber matrix, an optional oil, and one or more components selected from the group consisting of carbon black, vulcanizing agent, vulcanization accelerator, tackifier resin, antioxidant, wax, peptizer, vulcanization retarder, activator, processing additive, plasticizer, pigments, and antiozonant. A method for making the rubber composition and the tire tread is also provided.
