  • Dicyclopentadiene polymers with heat-resistant dimensional integrity and high T.sub.g
    Patent number: 5268232
    Abstract: A molded article comprising a cross-linked ring-opened polymer produced by the metathesis polymerization of a dicyclopentadiene (DCPD) monomer, which may be dicyclopentadiene (DCPD) or of a mixture of (DCPD) and norbornene group-containing cycloolefins, in the presence of an effective amount of a metathesis polymerization catalyst and a co catalyst that is capable of crosslinking the unsaturated double bonds of the polymer and thereby increasing the crosslink density of the polymer and its T.sub.g, a process for making it, a process for increasing the T.sub.g of the molded article, and uses of the molded article with a high T.sub.g.
