Abstract
The oil extended styrene-isoprene-butadiene rubber was synthesized using organic lithium as initiator, and cyclohexane-hexane mixture as solvent. The effect of different mass ratio of monomer and styrene micro-block on the properties of copolymer were also discussed. The SIBR was produced by mixing with aromatic oil at 500 L scale pilot plant. The structure, properties of the oil-extended SIBR and its application in green tire were investigated. The results showed the mixing behavior, vulcanization rate, mechanical properties, rolling loss and wet skid resistance of SIBR are excellent, which indicate that styrene(St)-isoprene(Ip)-butadiene(Bd) copolymer (SIBR) have a good application prospect for tread rubber.
