    摘要: This invention pertains to the use of organoammonium, organophosphonium, organoarsonium heteropolymolybdates and heteropolytungstates, and mixtures thereof, as catalysts in a metathesis catalyst system in polymerization of cycloolefin monomers by ring opening polymerization. Polymerization can be by reaction injection molding in absence of a solvent whereby a thermoset polymer is produced or by solution polymerization in presence of a suitable solvent whereby a thermosetting or a thermoplastic polymer is produced. The cycloolefin monomers are selected from monocycloolefins except cyclohexane, polycycloolefins containing at least one norbornene group, and mixtures thereof.
