Abstract
A method of making a thermoset polydicyclopentadiene by first combining a plurality of reactant streams, one containing the activator of a metathesis-catalyst system, a second containing the catalyst of a metathesis-catalyst system and at least one containing dicyclopentadiene; then immediately injecting this combination into a mold where polymerization results in the formation of a tough, rigid thermoset polymer with high modulus and excellent impact strength.
Claims16
A method of making a thermoset homopolymer comprising:
- first, combining a plurality of reactant streams, one of which contains the activator of a metathesis-catalyst system combined with a moderator, and a second which contains the catalyst of said metathesis-catalyst system and at least one of which contains dicyclopentadiene to form a reaction mixture and then, immediately injecting the reaction mixture into a mold where polymerization occurs.
