An Olefin Metathesis Polymerization Catalyst System And Curable Compositions Containing The Catalyst System

Abstract: disclosed is an olefin metathesis polymerization catalyst system. the catalyst system comprises a metalate as pre-catalyst and an aluminum complex as co-catalyst, wherein the aluminum complex is an alkoxyalkylaluminum halide complex [(or)(r)alx]wherein oris an alkoxy ligand derivable from an alcohol with a pka in the range of from 18-30, wherein the alkoxy is optionally functionalized and wherein further n is an integer in the range of from 1-3, ris an alkyl, and xis an halide. also disclosed is a method of manufacturing a molded article of a curable composition comprising the catalyst system. the method comprises providing the curable composition by combining the cyclic olefin and the olefin metathesis polymerization catalyst system in a mold; subjecting the composition to conditions effective to promote an olefin metathesis reaction of the cyclic olefin in the closed mold; and taking the reacted composition out of the mold to obtain the molded article. with the method a thin-walled article of a cyclic olefin polymer may be obtained having a glass transition temperature tabove 60� c.
