Abstract: The present disclosure provides methods for producing an olefin polymer by contacting a C3-C40 olefin, ethylene and a diene with a catalyst system including an activator and a metallocene catalyst compound comprising a substituted or unsubstituted indacenyl group and obtaining a C3-C40 olefin-ethylene-diene terpolymer typically comprising from 1 to 35 mol % of ethylene, from 98.9 to 65 mol % C3-C40 olefin, and, optionally, from 0.1 to 10 mol % diene. Preferably, a propylene-ethylene-ethylidene norbornene is obtained.

Abstract: Unsaturated polyalpha-olefin (uPAO) materials comprising a mixture of vinylidene olefins, 1,2-di-substituted vinylene olefins, and tri-substituted vinylene olefins. The unsaturated PAO material can be made from alpha-olefin monomer(s) in the presence of a metallocene-compound-based catalyst system. The unsaturated PAO material can be used as intermediate material for making PAO materials having functional groups.

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

CPC classification number: C08F4/65912 , C08F10/06 , C08F4/65908
Abstract: This invention relates to a homogeneous process to produce propylene polymers using transition metal complexes of a dianionic, tridentate ligand that features a central neutral heterocyclic Lewis base and two phenolate donors, where the tridentate ligand coordinates to the metal center to form two eight-membered rings. Preferably the bis(phenolate) complexes are represented by Formula (I):
where M, L, X, m, n, E, E′, Q, R1, R2, R3, R4, R1′, R2′, R3′, R4′, A1, A1′,
and
are as defined herein, where A1QA1′ are part of a heterocyclic Lewis base containing 4 to 40 non-hydrogen atoms that links A2 to A2′ via a 3-atom bridge with Q being the central atom of the 3-atom bridge.-
