    摘要： Elastomeric compositions comprising at least one C4 to C7 monoolefin elastomer, at least one polyalphaolefin, and optionally at least one hydrocarbon polymer additive are disclosed. The PAO comprises oligomers of one or more C2 to C20 alpha-olefins having a kinematic viscosity at 100° C. of 3 to 3000 cSt and a Mw/Mn of less than 4. In one aspect, the elastomeric composition may have improved flex fatigue properties and have a fatigue life of 450,000 Kc or more as measured by ASTM D 412 die C. In another aspect, an elastomeric composition may have improved impermeability and have a permeation coefficient at 40° C. of 160 cc*mm/(m2−day) or less.

    摘要： The invention relates to a truck or bus tire with a rubber tread of cap/base construction where the tread cap is composed of an emulsion polymerization prepared styrene/butadiene copolymer elastomer with a relatively random styrene content (E-SBR-A). Such E-SBR-A, in its uncured state, also has a relatively low Tg. In one aspect, the tire tread's tread cap may also be a blend of elastomers such as cis 1,4-polybutadiene and/or natural rubber together with said E-SBR-A and wherein the tread base elastomer is composed primarily of natural cis 1,4-polyisoprene rubber. In another aspect of the invention, said tread cap has a tread design composed of at least three circumferential continuous ribs designed to be road contacting, said ribs independently separated by continuous, circumferential grooves.

    摘要： An elastomeric composition for a curing bladder comprises isobutylene based elastomer, curative and a hydrocarbon polymer modifier comprising monomers selected from the group consisting of piperylenes, cyclic pentadienes, aromatics, limonenes, pinenes, amylenes, and combinations thereof, wherein the cyclic pentadienes comprise at least 10 weight percent of the monomers by total weight of the monomers. Also disclosed are a tire curing bladder made from the elastomeric composition, a tire curing press containing the bladder, a method of making the tire curing bladder, an improvement to the process of making the tire curing bladder to improve processability of the mixture and fatigue life and DeMattia cut growth, a method of making a tire using the tire curing bladder, and an improvement to the process of making a tire to extend a pull point of the curing bladder and/or to reduce the curing time for the tire construct.
