Abstract: A method of ring-opening metathesis polymerization (ROMP) may comprise: contacting a first cyclic olefin comonomer to the reaction mixture over time at a rate of 0.01 mol% per minute to 25 mol% per minute based on a total amount of the second cyclic olefin comonomer added to the reaction mixture to produce a polymer, wherein a final mol to mol ratio of first cyclic olefin comonomer to second cyclic olefin comonomer added to the reaction mixture is 1:1 to 500:1; and wherein the second cyclic olefin comonomer has a higher reactivity with the metathesis catalyst than the first cyclic olefin comonomer.

Abstract: A supported catalyst system is based on a transition metal carbene including the moiety Ml=CR*) 2 , wherein M 1 is the transition metal and R* is hydrogen or a C1-C8 hydrocarbyl. The catalyst system can be supported on a metal oxide support such as silica or the catalyst can be self-supporting. Methods of making the catalyst system can involve precursors based on and/or reacted with aluminum alkyls, halides, and/or alkoxides. Methods of polymerizing cyclic olefins with the catalyst system can obtain polyalkenamers, cyclic olefin polymers, cyclic olefin copolymers, and other metathesis reaction products. The supported catalyst and/or monomer can be recovered and recycled to the polymerization reactor.

The catalyst includes a transition metal carbene having the following structure: Mv(OR')c*mX(v-c*m-2)=C(R*)2 wherein Mv is a Group 5 transition metal having a valence (v) of 5 or a Group 6 transition metal having a valence (v) of 5 or 6; each R' is independently a monovalent organic moiety comprising from 8 to 40 atoms selected from Groups 14-17; c is an integer from 1 to 3; m is 1/3, 1/2, 1, 3/2, 2, 3, or 4 and c*m ≤ v-2; X is a halogen; and each R* is independently H or a C1 to C7 alkyl. The catalyst is particularly useful for ring-opening metathesis polymerization (ROMP).
