摘要: Styrene–butadiene rubber (SBR) is a copolymer of styrene and butadiene, the butadiene unit composed cis-1,4-, trans-1,4-, 1,2-components. Filler-polymer interactions each component SBR in silica-filled compounds were examined by microstructure analysis bound unbound rubbers. The composition ratio units (butadiene/styrene) was higher than that compounded rubber. Of units, 1,2-component more abundant cis-1,4- trans-1,4-components. filler-polymer interaction with silica stronger unit, as compared others. butadiene–styrene containing silane coupling agent lower for without silane. © 2004 Wiley Periodicals, Inc.
