Abstract
This invention relates to novel resins, blends of the novel resins with base polymers and a process for producing a resin comprising combining a reactor feed blend comprising:(a) at least 2 weight % of isoprene,(b) at least 2 weight % of one or more of dicyclopentadiene, substituted cyclopentadienes and substituted dicyclopentadienes,(c) at least 2 weight % piperylene,(d) at least 1 weight % aromatic olefins, and(e) 0 to 92 weight % of additional aliphatic olefins, based upon the weight of the reactor feed blend, with a polymerization catalyst under polymerization conditions, preferably where the ratio of component (c) to component (b) is less than 8 and the ratio of component (a) to component (b) is less than 5.
