    摘要: Disclosed herein are catalyst compositions and polymers, i.e., propylene-based polymers, produced therefrom. The present catalyst compositions contain an internal electron donor of an alkoxyalkyl 2-propenoate and optionally a mixed external electron donor. The present catalyst compositions improve catalyst selectivity and polymer stiffness. Polypropylene homopolymer produced from the present catalyst composition has a xylene solubles content less than 4 wt % and a TMF greater than 172.0° C.

    摘要: Activating supports may be suitably prepared by (a) combining (i) fluorine-containing compounds having a reactive group and (ii) an organometallic compound, (b) addition of a porous mineral oxide support material, (c) heating the functionalized support from step (b) under an inert gas and then under an atmosphere comprising oxygen, and (d) recovering the activating support. The preferred fluorine-containing compounds have the formula: R(Fn)-X wherein R is hydrocarbyl, substituted hydrocarbyl, heterohydrocarbyl or substituted heterohydrocarbyl with up to 20 non-hydrogen atoms, n is 1-41, X is OH, SH or NR′2, R′ is hydrogen or hydrocarbyl. The activating supports are suitable used in combination with transition metal catalysts for the polymerization of olefins. The supports are most preferable used in combination with metallocene complexes. The preparative route for the activating supports is easier and more economic than prior art methods and also provides for supported polymerization catalyst systems having excellent activities. Polymers produced by use of the activating supports exhibit improved rheology properties.

    摘要: Supported catalyst system for the polymerization of olefins, having at least two different monocyclopentadienyl transition metal compounds, one or more activators including an ionic compound having (i) a cation and (ii) an anion having up to 100 non-hydrogen atoms and the anion containing at least one substituent comprising a moiety having an active hydrogen, and one or more support materials. The supported “mixed or dual site” catalyst systems having different monocyclopentadienyl catalysts when activated by specific ionic activators lead to catalyst systems showing an improved balance of properties which may be used to prepare LLDPE polymers having broad melt flow ratios.
