Abstract: Metallocene complexes represented by the structure below are useful for alpha olefin oligomerization in the presence of an activator to generate polyalphaolefins having a high percentage of vinylidene termination and relatively low Mn values. M is a group 4 transition metal. A is a bridging group having one bridging atom extending between a first indenyl ring and a second indenyl ring. Each X is independently an anionic ligand, or two Xs are joined and bound to M to form a metallocycle ring, or two Xs are joined to form a chelating ligand, a diene ligand, or an alkylidene ligand. R1, R1?, R3, R3?, R4, R4?, R7 and R7? are hydrogen. R5, R5?, R6, and R6? are independently a C1-C10, optionally substituted, hydrocarbyl group, or R5 and R6 and/or R5? and R6? are bonded together to form an optionally substituted hydrocarbyl ring structure.

Abstract: A metal complex of the formula (1) TCyLMZp (1), wherein M is a group 4 metal, Z is an anionic ligand, p is the number 1 or 2, TCy is a thiophene-fused cyclopentadienyl-type ligand of the formula (2) is described. Methods of making and using the metal complex are also described.

Abstract: The present invention provides a compound according to formula (I): (I) wherein: •R2 is abridging moiety containing at least one sp2 hybridised carbon atom; •each R4, R4?, R7 and R7? are hydrogen or moieties comprising 1-10 carbon atoms, wherein each R4, R4?, R7 and R7? are the same; •each R5, R5?, R6 and R6? are moieties comprising 1-10 carbon atoms, wherein each R5, R5?, R6 and R6? are the same; and •Z is a moiety selected from ZrX2, HfX2, or TiX2, wherein X is selected from the group of halogens, alkyls, aryls and aralkyls. Such compound allows for the preparation of catalyst systems that provide improved olefin reactivity, such as ethylene reactivity, increased molecular weight in olefin polymerisation, such as increased Mw in ethylene polymerisation, and increased comonomer incorporation in copolymerisation reactions of olefins, such as in copolymerisation reactions of ethylene with 1-hexene.

Abstract: The present disclosure relates to Lewis base catalysts. Catalysts, catalyst systems, and processes of the present disclosure can provide high temperature ethylene polymerization, propylene polymerization, or copolymerization as the Lewis base catalysts can be stable at high polymerization temperatures and have good activity at the high polymerization temperatures. The stable catalysts with good activity can provide formation of polymers having high melting points, high isotacticity, and controllable molecular weights, and the ability to make an increased amount of polymer in a given reactor, as compared to conventional catalysts. Hence, the present disclosure demonstrates highly active catalysts capable of operating at high reactor temperatures while producing polymers with controlled molecular weights and or robust isotacticity.
