A DICYCLOPENTADIENE THERMOSET POLYMER AND A CATALYST AND A METHOD FOR MAKING IT

摘要

A high impact strength, high modulus thermoset homopolymer is formed by the metathesis-catalyzed polymerization of dicyclopentadiene. In a preferred embodiment of the synthesis two parts of a metathesis-catalyst system, a catalyst/monomer solution and an activator/monomer solution, are combined in the mixing head of a reaction injection molding machine and then injected into a mold. The reaction mixture sets up into a tough, rigid, thermoset polymer with high modulus and excellent impact strength.
