Abstract:
A resin composition comprising the copolymerization reaction product of a monomer mixture comprising: (1) about 5% to about 25% by weight of a monomer compound of the formula: wherein R1 is H, C1-10 linear or branched aliphatic or aromatic, OH or OR, wherein R is alkyl or acyl; and (2) about 75% to about 95% by weight of a cyclic diolefin component comprising at least about 50% by weight dicyclopentadiene, wherein the resin has a Mz of less than about 2,000, said resin made by the process comprising the steps of (i) providing a solvent to a reactor; (ii) heating said solvent to a temperature of about 200Â° C. to about 265Â° C.; and (iii) adding the monomer mixture to the reactor, at a rate such that the concentration of free monomer compound of formula I in the reactor is held at a minimum at any given time of the reaction to minimize the formation of monomer compound homopolymer.
