Abstract
A crosslinked polymer composition obtained by the metathesis polymerization of a dicyclopentadiene monomer in which a chlorinated polymer such as a chlorinated elastomer or chlorinated polypropylene is dissolved; a crosslinked dicyclopentadiene polymer composition comprising a ring-opened dicyclopentadiene polymer and a dicyclopentadiene-soluble chlorinated polymer; and a method for preparing a crosslinked polymer composition comprising adding the chlorinated polymer to one of two reactant liquid streams, one of which contains dicyclopentadiene and a ring-opening metathesis catalyst and the other contains a catalyst activator, combining the two streams, and charging them to a mold or similar forming container in which the dicyclopentadiene polymerizes.
