摘要： This invention is based upon the finding that a hydrocarbon traction resin can be dispersed into the oil used in making an oil extended emulsion and solution rubbers to attain improved performance characteristics. For instance, this technique allows for the hydrocarbon traction resin to be incorporated into the rubber at a higher level than would ordinarily be possible using conventional mixing techniques. In tire tread compounds this provides improved wet traction characteristics without compromising cured stiffness (dry traction) and ultimate properties (chip/chunk resistance). This technique can be used to incorporate a resin into virtually any synthetic rubber that can benefit from being oil extended. More specifically, this invention is applicable to making resin modified oil extended rubbers comprising solution polymerized styrene-butadiene rubber (SSBR), emulsion polymerized styrene-butadiene rubber (ESBR), polybutadiene rubber, synthetic polyisoprene rubber, ethylenepropylene-diene rubber (EPDM), isoprene-butadiene rubber, styrene-isoprene-butadiene rubber, silicon rubber, nitrile rubber, carboxylated nitrile rubber, and the like. It is of particular value in making resin modified solution polymerized styrene-butadiene rubber (SSBR), emulsion polymerized styrene-butadiene rubber (ESBR), high cis-1.4-polybutadiene rubber, and synthetic polyisoprene rubber which are formulated for use in tire tread compounds.
