Abstract: This invention relates to a process to produce an ionomer comprising: 1) contacting, in a reactor, one or more C2-C60 α-olefins, an optional diene, and a metal alkenyl with a catalyst system comprising an activator, a catalyst compound, and a support; 2) forming a copolymer comprising one or more C2-C60 α-olefin monomers and about 0.01 wt % to about 20 wt %, based on the weight of the copolymer, of metal alkenyl; 3) functionalizing and quenching the polymerization reaction with one or more electrophilic groups; and 4) obtaining ionomer.

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.

Abstract: A composition, including: a copolymer including units derived from ethylene, one or more α-olefins, one or more substituted styrene compounds, and a pendant alkoxy silane group. A method was disclosed to incorporate pendant alkoxy silyl groups onto the benzylic positions. The silane-functionalized polymers show ability to cure with water. Additionally, blends of silane-functionalized polymers exhibit improved filler acceptance.

Abstract: Vinylcyclobutane (VCB) homopolymers, VCB copolymers and processes for making same. The VCB homopolymers and copolymers have a polydispersity (PDI) of less than 3.0 and are made by contacting VCB monomer in the presence of a single-site metallocene, post metallocene, or half metallocene, and an activator, under sufficient reaction conditions to produce a VCB (co)polymer having the narrow PDI of less than 3.0. The resulting poly(vinylcyclobutane) polymers have increased crystallinity and melting point properties (Tm of 165° C. to 246° C.) that are comparable to conventional polyolefins such as polyethylene (typical Tm
