    摘要: This invention relates to a novel class of polymeric resins which have a softening point ranging from about 50° C. to about 220° C. and a molecular weight ranging from about 500 to about 42,000. The resins consist essentially of the polymers which result from the polymerization reaction between dicyclopentadiene and limonene. The polymeric resins are particularly useful in improving traction of the rubber when used in tire treads.

    摘要: The present invention relates to asymmetrical siloxy compounds of the formula wherein R1, R2 and R3 are independently selected from the group consisting of alkoxy radicals having from 1 to 8 carbon atoms; and R4 is selected from the group consisting of substituted or unsubstituted alkylene groups having from 1 to 18 carbon atoms and arylene and alkyl substituted arylene groups having from 6 to 12 carbon atoms. The asymmetrical siloxy disulfide compounds are prepared from N-cyclohexylthiophthalimide and a mercaptoalkoxysilane.
