Abstract
The present invention relates to methods and compositions for olefin metathesis. More particularly, the present invention relates to methods and compositions for ring opening metathesis polymerization (ROMP) reactions and the manufacture of polymer articles and/or polymer composite articles via ROMP Polymer products produced via the metathesis reactions of the invention may be utilized in a wide range of materials and composite applications. The invention has utility in the fields of polymer and materials chemistry and manufacture.
Claims14
A ring opening metathesis polymerization (ROMP) composition, comprising a catalyst composition comprising at least one metal carbene olefin metathesis catalyst, and a resin composition comprising a cyclic olefin composition, wherein the cyclic olefin composition comprises 35.00% to 70.00% by weight tricyclopentadiene, 0.01% to 4.00% by weight tetracyclopentadiene, and up to 64.99% by weight of one or more other cyclic olefins.
A method for making a ring opening metathesis polymerization (ROMP) polymer, comprising providing a catalyst composition comprising at least one metal carbene olefin metathesis catalyst, providing a resin composition comprising a cyclic olefin composition, wherein the cyclic olefin composition comprises 35.00% to 70.00% by weight tricyclopentadiene, 0.01% to 4.00% by weight tetracyclopentadiene, and up to 64.99% by weight of one or more other cyclic olefins, combining the catalyst composition and the resin composition to form a ROMP composition, and subjecting the ROMP composition to conditions effective to promote polymerization of the ROMP composition.
