Publication number: 20230046273Abstract: This invention is based upon the unexpected 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. It is of particular value in making resin modified solution styrene-butadiene rubber (SSBR), emulsion styrene-butadiene rubber (ESBR), high cis-1.4-polybutadiene rubber, and synthetic polyisoprene rubber which are formulated for use in tire tread compounds.Type: ApplicationFiled: October 10, 2022Publication date: February 16, 2023Inventors: Nihat Ali Isitman, Robert Alan Woloszynek, Joseph John Kulig, Hannah Long, Manuela Pompei, Jennifer Labbe
