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

The present application relates to polymeric resinous material comprising
(1) from 5 to 70 weight percent units derived from limonene; (2) from 5 to 70 weight percent units derived from dicyclopentadiene; (3) from 5 to 45 weight percent units derived from indene; and (4) from 5 to 45 weight percent units derived from vinyl toluene; wherein the sum of the weight percent units derived from limonene and dicyclopentadiene range from 40 to 75 weight percent units of the resin and the sum of the weight percent units derived from indene and vinyl toluene range from 25 to 60 weight percent units of the resin.
