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 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.
摘要:
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 tertiary-butyl styrene; 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 tertiary-butyl styrene range from 25 to 60 weight percent units of the resin.
摘要:
The present application relates to polymeric resinous material comprising (1) from 15 to 39 weight percent units derived from limonene; (2) from 15 to 39 weight percent units derived from dicyclopentadiene; and (3) from 46 to 70 weight percent units derived from tertiary-butyl styrene; wherein the sum of the weight percent units derived from limonene and dicyclopentadiene range from 30 to 54 weight percent units of the resin.
