    摘要： A carbon black reinforced rubber composition which contains hydrophilic sorbitan monostearate and specialized tackifying resin and a pneumatic rubber tire having a visually observable rubber component, such as for example a rubber sidewall, of said rubber composition. The surface of said rubber composition, namely the tire sidewall rubber component, in its uncured state contains said hydrophilic sorbitan monostearate on its surface together with said specialized tackifying resin to promote enhanced building tack and thereby counteract building tack loss by the sorbitan monostearate having been exposed to moisture (moisture exposed surface) during the processing of the rubber composition, particularly after its high shear processing such as, for example, extrusion.

    摘要： The invention relates to a tire having at least one component (e.g. tread) of a rubber composition comprised of an amine functionalized styrene/conjugated diene copolymer elastomer (e.g. styrene/butadiene and/or styrene/isoprene/butadiene copolymer elastomer) which contains reinforcement comprised of silanol functionalized particulate carbon black having silica domains covering a fraction of the carbon black surface together with an alkoxysilane polysulfide coupling agent. The silica domains on the carbon black surface contain hydroxyl groups (e.g. silanol groups) on their surfaces which are reactive with the alkoxysilane moiety of the coupling agent. The amine functionalized styrene/butadiene elastomer is an organic solution polymerization prepared elastomer which contains pendant and/or terminal amine groups as one or more of primary amine, secondary amine, tertiary amine, and/or heterocyclic amine groups. The amine functionalized elastomer may be tin coupled.

    摘要： Sidewalls of a pneumatic tire have greater resistance to failure due to dynamic flexing and abrasion, and the tire's tread has better resistance to tearing than with conventionally used rubber compositions, when sidewalls and tread are formed from a compound having a major proportion by weight of synthetic rubber (SR) and a minor proportion by weight of natural rubber (NR), and a major proportion by weight of the SR itself consists essentially of a high cis-1,4-polybutadiene having defined molecular architecture. The high cis-1,4-PBD has more than 90 percent cis-structure, a poly-dispersity in the range from about 3 to 5, a number average molecular weight Mn in the range from 100,000 to 150,000 and a degree of branching in the range from 2 to 3.5. The sidewall compound has characteristics quite different from one made with a typical commercially available high cis-1,4-PBD; and the tread has excellent tear strength. The dendritic structure of the high HI cis-1,4-PBD molecules has an unexpectedly beneficial effect on the performance characteristics of the sidewall and tread, particularly important in a high-performance automobile tire.

    摘要： In tire tread formulations, blends of rubbers having low and high glass transition temperatures have significant advantages over blends made with rubbers having intermediate glass transition temperatures. However, blends of rubbers having low and high glass transition temperatures exhibit poor processability. This invention deals with improving the processability of tire tread formulations which are made by blending rubbers having both low and high glass transition temperatures that offer ultra low rolling resistance without sacrificing rolling resistance or tread wear characteristics. This invention more specifically discloses a tire tread rubber composition which is comprised of (a) about 60 phr to about 90 phr of a high cis-1,4-polybutadiene rubber, wherein the high cis-1,4-polybutadiene rubber has a glass transition temperature which is within the range of about −104° C. to about −80° C., (b) about 10 phr to about 40 phr of at least one additional rubbery polymer selected from the group consisting of polyisoprene rubber, polybutadiene rubber and styrene-isoprene-butadiene rubber, wherein the additional rubbery polymer has a glass transition temperature which is within the range of about −30° C. to about −10° C. isoprene-butadiene rubber, (c) about 20 phr to about 60 phr of carbon black, wherein the carbon black has a DBP absorption value of at least 140 cm3/100 grams and wherein the carbon black has a CTAB adsorption area which is within the range of about 60 to about 90.
