    摘要: A series of soluble α-diimine late transition metal catalysts has been invented. The catalysts demonstrate high activity and selectivity for linear α-olefins. As such, these catalysts conveniently oligomerize ethylene. Typical activators as known to those of ordinary skill in the art are used to activate these transition metal catalyst. These catalysts can be used in a supported or unsupported form.

    摘要: A This invention relates to a composition comprising a catecholate ligand, palladium or nickel, and an ancillary ligand with the following structure: where Pn is a Group-15 element; H is hydrogen; R7 and R8 are independently hydrogen or C1-C30 hydrocarbyl radicals, or both are C1-C30 hydrocarbyl radicals that form a ring structure comprising one or more aromatic or non-aromatic rings; and R13-R18 are, independently, hydrogen or C1-C30 hydrocarbyl radicals. The composition can be used to oligomerize ethylene.

    摘要: A series of soluble α-diimine late transition metal catalysts has been invented comprising a substituted or unsubstituted catecholate ligand. The catalysts demonstrate high activity and selectivity for linear α-olefins. As such, these catalysts conveniently oligomerize ethylene. Typical activators as known to those of ordinary skill in the art are used to activate these transition metal catalysts. These catalysts can be used in a supported or unsupported form.

    摘要: Substantially random ethylene and/or α-olefin copolymers containing units derived from vicinally disubstituted olefin monomers are described. The vicinally disubstituted olefin monomers may be represented by the generic formula (R1)CH═CH(R2), where R1 and R2 independently comprise hydrocarbyl or silyl-hydrocarbyl groups containing 1 or more carbon atoms, or may be linear, branched or cyclic substituted or unsubstituted hydrocarbyl groups having from 1-100 carbon atoms, or they may contain 30 or less carbon atoms. The copolymers may be prepared by coordination polymerization by means of contacting at least one vicinally disubstituted olefin monomer and ethylene and/or α-olefin, optionally with one or more other coordination polymerizable monomers, with a catalyst system comprising a monocyclopentadienyl heteroatom-containing Group 4 transition metal catalyst component.
