    摘要： A bimodal poly(ethylene-co-1-alkene) copolymer comprising a higher molecular weight poly(ethylene-co-1-alkene) copolymer component and a lower molecular weight poly(ethylene-co-1-alkene) copolymer component. The copolymer is characterized by a unique combination of features comprising, or reflected in, its component weight fraction amount, density, high load melt index, molecular weight distributions, viscoelastic properties, environmental stress-cracking resistance, and impact strength. Additional inventive embodiments include a method of making the copolymer, a formulation comprising the copolymer and at least one additive that is different than the copolymer, a method of making a manufactured article from the copolymer or formulation; the manufactured article made thereby, and use of the manufactured article.

    摘要： Process for the production of a supported metallocene catalyst system involving the steps of: (i) preparing a mixture (a) by subjecting a quantity of a metallocene compound of together with a quantity of a cocatalyst as solution in a hydrocarbon solvent, preferably at a temperature of 40-80°C for a period of 0.1-2.0 hrs; (ii) preparing a mixture (b) by reacting a quantity of an aluminium compound of formula (II) with a quantity of an amine compound of formula (III) in a hydrocarbon solvent; (II) (III) wherein R6 is hydrogen or a hydrocarbon moiety comprising 1 to 30 carbon atoms; each R7 and R8 are the same or different and are hydrocarbon moieties comprising 1 to 30 carbon atoms; R9 is hydrogen or a functional moiety comprising at least one active hydrogen; R10 is hydrogen or a hydrocarbon moiety comprising 1 to 30 carbon atoms; R11 is a hydrocarbon moiety comprising 1 to 30 carbon atoms; (iii) providing a quantity of a support material, preferably a dehydrated support materials, into a reaction vessel; (iv) providing a quantity of a hydrocarbon solvent into the reaction vessel; (v) supplying the mixture (a) and the mixture (b) to the reaction vessel; (vi) subjecting the contents of the reaction vessel to a temperature of > 60°C for a period of > 3 hrs to obtain a supported catalyst system; and (vii) removing the hydrocarbon solvent from the supported catalyst system. Such process allows for the production of a supported metallocene catalyst system having reduced fouling in olefin polymerisation.

    摘要： A method for making a propylene oligomer having a high vinylidene content and a high degree of structural regularity and the propylene oligomer made therefrom. The method of making the propylene oligomer comprises contacting an unbridged metallocene complex with a propylene composition in the presence of a modified methyl aluminum oxide activator compound under suitable oligomerization conditions. The use of the combination of a modified methyl aluminum oxide activator compound with an unbridged metallocene complex has been found to provide increased vinylidene group content and reduced hydrogenated propylene oligomer content.
