Abstract: A process for making a poly alpha-olefin (PAO) having a relatively high vinylidene content (or combined vinylidene and tri-substituted vinylene content) and a relatively low vinyl and/or di-substituted vinylene content, as well as a relatively low molecular weight. The process includes: contacting a feed containing a C2-C32 alpha-olefin with a catalyst system comprising activator and a bis-cyclopentadienyl metallocene compound, typically a cyclopentadienyl-benzindenyl group 4 transition metal compound.

Abstract: Provided herein are methods of making blended polymer compositions having enhanced elasticity. The present methods comprise the steps of producing a first polymer composition using a VTP catalyst system, producing a second polymer composition using a HMP catalyst system and combining the first polymer composition and the second polymer composition to make the blended polymer composition. The present methods include blending/combining the polymer compositions produced by different catalyst systems. One such catalyst system includes (i) a vinyl-terminated polymer (VTP) catalyst system comprising a VTP catalyst compound (referred to herein also as a “VTP catalyst”) and one or more activators. Another catalyst system includes a high molecular-weight polymer (HMP) catalyst system comprising a HMP catalyst compound (referred to herein also as a “HMP catalyst”) and one or more activators. The activators of these different catalyst systems can be the same or different in whole or in part.

Abstract: This invention relates to a process to produce cyclic olefin containing polymer compositions 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′, A3A2, and A2′A3′ 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.

Abstract: The alkylation of transition metal coordination catalyst complexes (such as metallocenes and/or post-metallocenes) in non-polar solvents with high conversion to the dialkylated transition metal coordination catalyst complex may be accomplished by reacting (a) a transition metal coordination catalyst complex comprising a transition metal linked to at least one an anionic donor ligand and at least one leaving group having a non-carbon atom directly linked to the transition metal, (b) an aluminum alkyl, and (c) a fluoride salt at 0° C. to 85° C. in a non-polar solvent to yield an alkylated transition metal coordination catalyst complex.
