摘要：This invention discloses a rubber composition having a high modulus andexcellent processability which is comprised of a blend of (1) at least one elastomerselected from the group consisting of polybutadiene rubber, styrene-butadiene rubber,synthetic polyisoprene rubber, natural rubber, isoprene-butadiene rubber, isoprene-butadiene- styrene rubber, nitrile rubber, carboxylated nitrile rubber, and EPDM rubber,(2) at least one thermotropic liquid crystalline polymer containing an aliphatic spacer,wherein the thermotropic liquid crystalline polymer exhibits no apparent crystalline tonematic transition, wherein the thermotropic liquid crystalline polymer exhibits nematicorder above its glass transition temperature, and wherein the glass transitiontemperature of the thermotropic liquid crystalline polymer is within the range of 20.degree. C. to 180° C., and (3) carbon black.
