Abstract:
A reinforced polyolefin article comprising:a) a reinforcing material selected from the group consisting of barium sulfate, glass, carbon, graphite, ceramic, boron, metallic materials, organic polymers, polyolefins, and fluoropolymers, wherein the reinforcing material is at least partially coated with a compatible coupling agent selected from the group consisting of chromium, silane, titanate, zirconate, and zircoaluminate; andwherein the coupling agent is functionalized with at least one functional group, with the proviso that the compatible coupling agent is other than a functionalized silane having a primary amine functional group or a terminal epoxide functional group;b) a polyolefin prepared by polymerizing a cyclic olefin monomer in the presence of a metathesis polymerization catalyst of the formula: ##STR6##wherein:M is ruthenium or osmium;X and X.sup.1 are either the same or different and are any anionic ligand;L and L.sup.1 are either the same or different and are any neutral electron donor;R and R.sup.1 are either the same or different and are each independently hydrogen or a substituent selected from the group consisting of C.sub.1 -C.sub.20 alkyl, C.sub.2 -C.sub.20 alkenyl, C.sub.2 -C.sub.20 alkynyl, aryl, C.sub.1 -C.sub.20 carboxylate, C.sub.1 -C.sub.20 alkoxy, C.sub.2 -C.sub.20 alkenyloxy, C.sub.2 -C.sub.20 alkynyloxy, aryloxy, C.sub.2 -C.sub.20 alkoxycarbonyl, C.sub.1 -C.sub.20 alkylthio, C.sub.1 -C.sub.20 alkylsulfonyl and C.sub.1 -C.sub.20 alkylsulfinyl, wherein each of the substituents is substituted or unsubstituted; andwherein the monomer includes an additive selected from the group consisting of fillers, binders, plasticizers., pigments and dyes; and wherein the coupling agent is disposed between the reinforcing material and the polyolefin.
