Title:
【発明の名称】シクロオレフィンポリマーの製造方法
Document Type and Number:
Japanese Patent JP2847555
Kind Code:
B2
Abstract:
This invention pertains to the use of organophosphonium and organoarsonium molybdates and tungstates 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 polycycloolefins containing at least one norbornene group, and mixtures thereof.
