Random styrene-butadiene copolymer rubber |
摘要 |
A random SBR having excellent tensile strength, resilience, and abrasion resistance as well as a reduced heat buildup property, which comprises 10% to 40% by weight of styrene units and the balance of butadiene units and has a Mooney viscosity of 30 to 150; a content of butadiene units having 1,2-vinyl structure of 60% or less; a ratio &upbar& M/ &upbar& M of from 1.2 to 3.5; and a content of isolated styrene units of 40% or more and a content of another styrene units in long chain block form of 5% or less, both contents being determined by decomposing the copolymer with ozone and by applying a gel permeation chromatographic analysis to the ozone decomposition product.
