  • SILANE MODIFIED STYRENE BUTADIENE COPOLYMER FOR HIGH PERFORMANCE IN DRY ADHERENCE, WET ADHERENCE AND ROLLING RESISTANCE
    Publication number: 20220033627
    Abstract: A curable rubber composition is provided which includes a high molecular weight diene elastomer; an optional carbon black composition; a silica composition; and a silane terminated copolymer different from the high molecular weight diene elastomer including conjugated dienes and vinyl aromatics as polymerized monomers. The silane terminated copolymer has at least one terminal end modified with at least one silane group and the silane terminated copolymer has a number average molecular weight of from 1,000 g/mol to 40,000 g/mol. A method for producing a rubber composition for use in a tire is provided. The method includes forming a composition by mixing the silane terminated copolymer modified with at least one silane group, a silica composition, a high molecular weight diene elastomer different from the silane terminated copolymer, and optionally a carbon black composition; and curing the composition.
