Patent application numberDescriptionPublished
20090018290Preparation of Supported Silyl-Capped Silica-Bound Anion Activators and Associated Catalysts - A method for the preparation of olefin polymerization catalysts that are the reaction products of the catalytic reaction of surface hydroxyls of a support with a trialkyl silane to afford hydrogen and the corresponding surface bound alkyl silyl ether and at the same time with a strong Lewis acid which support is converted to a silica bound anion that in a second step is fully converted by reaction with QM01-15-2009
20090306281Polyolefin Adhesive Compositions and Articles Made Therefrom - Provided are adhesive compositions composed of a polyolefin composition comprising at least about 50 wt. % polypropylene and at least one wax. The polymer compositions have a Dot T-Peel of about 1 Newton or more, a branching index (g′) of 0.95 or less measured at the Mz of the polymer, a molecular weight of 100,000 or less, and the adhesive compositions has a fast set time. The packaging industry desires adhesive compositions having a fast set time, such as those setting in less than five seconds from a molten state at conventional packaging operating temperatures to a solid or quasi solid having favorable Dot T-Peel, set time, and or fiber tear adhesion properties. Polymer based adhesives performing within this window are a favorable alternative to conventional formulated adhesives. The provided adhesive compositions exhibit a favorable balance of properties such as high adhesive strength, wide temperature operating window, and fast set time.12-10-2009
20100029873Catalyst System And Process For Olefin Polymerization - The present application relates to a new catalyst system for the polymerization of olefins, comprising a new ionic activator having the formula: [R02-04-2010
20100059178Polyolefin Adhesive Compositions - An adhesive and method for hot melt application. The adhesive comprises polyolefin base polymer, from 1 to 10 wt % of at least one functionalized polyolefin, and from 1 to 15 wt % of a wax, based on the total weight of the polyolefin base polymer, functionalized polyolefin and wax, wherein the wax has a weight average molecular weight at least 8% of the weight average molecular weight of the polyolefin base polymer, viscosity at 190° C. of 60 mPa·s or more, and a crystallization temperature greater than the polyolefin base polymer and greater than 100° C., and wherein the adhesive has at least 5% fiber tear at 2° C., at least 50% fiber tear at 25° C., and a characteristic set time of less than 3 seconds.03-11-2010
20100063227CATALYST SYSTEMS AND POLYMERIZATION PROCESSES - A method of polymerizing olefins with catalyst systems, such as, for example, a multimodal catalyst system, wherein the catalyst system is stored at a controlled temperature to minimize loss of catalyst system productivity.03-11-2010
20100132886Polyolefin Adhesive Compositions - An adhesive and method for hot melt adhesive application. The adhesive comprises polyolefin base polymer and from 1 to 15 wt % of a at least two wax components, based on the total weight of the polyolefin base polymer and the at least two wax components, wherein the at least two wax components comprise a first wax component having a relatively low weight average molecular weight at least 1000 g/mole less than a second wax component having a relatively high weight average molecular weight. The adhesive may have at least 50% fiber tear at 25° C., and a characteristic set time of less than 3 seconds. The adhesive may also include from 1 to 10 wt % of at least one functionalized polyolefin.06-03-2010
