Abstract: An improved catalyst for cyclic olefin polymerization. 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 ⅓, ½, 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).

Abstract: Elastomeric polyolefin-based ionomers and methods for making same. The ionomers can include a copolymer comprising: C2-C60 α-olefin monomer units; optional C2-C60 α-olefin comonomer units different than the monomer units; optional diene units; and about 0.1 wt % to about 20 wt % metal alkenyl units, based on the weight of the copolymer, wherein the metal alkenyl units have the formula —R(A−)—, wherein R is an alkyl group containing 2 to 10 carbon atoms, and A− is an anionic group. The copolymer can further include one or more metal cations derived from the group consisting of alkali metals, alkaline earth metals, group 3-12 metals, group 13-16 metals, and combination(s) thereof. The ionomer has a glass transition temperature of −60° C. to 5° C., and a weight average (Mw) of 50 to 5,000 kg/mol.
