  • Styrene-isoprene-butadiene rubber
    Patent number: 5317062
    Abstract: The subject invention discloses a styrene-isoprene-butadiene rubber which is particularly valuable for use in making truck tire treads, said rubber being comprised of repeat units which are derived from about 5 weight percent to about 20 weight percent styrene, from about 7 weight percent to about 35 weight percent isoprene, and from about 55 weight percent to about 88 weight percent 1,3-butadiene, wherein the repeat units derived from styrene, isoprene and 1,3-butadiene are in essentially random order, wherein from about 25% to about 40% of the repeat units derived from the 1,3-butadiene are of the cis-microstructure, wherein from about 40% to about 60% of the repeat units derived from the 1,3-butadiene are of the trans-microstructure, wherein from about 5% to about 25% of the repeat units derived from the 1,3-butadiene are of the vinyl-microstructure, wherein from about 75% to about 90% of the repeat units derived from the isoprene are of the 1,4-microstructure, wherein from about 10% to about 25% of the re
    Type: Grant
    Filed: July 14, 1993
    Date of Patent: May 31, 1994
    Assignee: The Goodyear Tire & Rubber Company

  • Styrene-butadiene rubber for truck tires
    Patent number: 5262213
    Abstract: The subject invention discloses a styrene-butadiene rubber (SBR) which is particularly valuable for use in making truck tire treads, said rubber being comprised of repeat units which are derived from about 10 weight percent to about 20 weight percent styrene and from about 80 weight percent to about 90 weight percent 1,3-butadiene, wherein the repeat units derived from styrene and 1,3-butadiene have a sequence distribution wherein at least about 55% of the styrene repeat units are in blocks of only one styrene repeat unit, wherein at least about 75% of the styrene repeat units are in blocks of 1 or 2 repeat units, and wherein at least about 5% of the styrene repeat units are in blocks of more than 8 repeat units, wherein from about 32% to about 40% of the repeat units derived from the 1,3-butadiene are of the cis-microstructure, wherein from about 50% to about 60% of the repeat units derived from the 1,3-butadiene are of the trans-microstructure, wherein from about 6% to about 15% of the repeat units derived
