| 20120085568 | REPLACEMENT PLASTICIZER SYSTEM FOR PHTHALATE-PLASTICIZED FORMULATIONS - The present invention is a replacement plasticizer system made from or containing an epoxidized fatty acid ester plasticizer as a primary plasticizer and a secondary plasticizer. The replacement placement system is useful with a variety of polymers in applications such as wire-and-cable insulations, wire-and-cable jackets, coatings, adhesives, and castings. | 04-12-2012 |
| 20110251361 | METHOD OF MAKING ZIEGLER-NATTA TYPE CATALYSTS - A process for making a Ziegler-Natta-type catalyst precursor including contacting a Group 4 metal compound with one or more Titanium compounds selected from the group of TiCl | 10-13-2011 |
| 20110152467 | Method of Crosslinking Carboxyl-Containing Polymers Using Oligoamines - Oligoamines, such as a compound of the formula H | 06-23-2011 |
| 20110130271 | ZIEGLER-NATTA CATALYST COMPOSITIONS FOR PRODUCING POLYETHYLENES WITH A HIGH MOLECULAR WEIGHT TAIL AND METHODS OF MAKING THE SAME - Methods of preparing a polymerization catalyst component is provided, in which a magnesium component, a Lewis acid solubilizing component, a titanium compound, optionally a transition metal compound different than the titanium compound, and typically an inert filler are combined in a slurrying agent and spray-dried to produce a catalyst precursor in the form of a substantially spherical and porous solid particle. The methods and catalysts of this disclosure can provide ethylene homopolymer and copolymer resins having a high molecular weight tail and a broadened molecular weight distribution as compared to more traditional Ziegler-Natta catalysts. | 06-02-2011 |
| 20110112250 | MOISTURE CROSSLINKABLE POLYETHYLENE COMPOSITION - The present invention is a moisture crosslinkable composition. It may be (i) a blend of a nonpolar polyolefin and a second highly polar or amorphous polyolefin or (ii) a copolymer of a nonpolar polyolefin and the second polar or amorphous polyolefin. The present invention is useful for the preparation of moisture-cured wires, cables, film, pipe, hot melt adhesives, and other extruded or injection molded articles. The present invention is also useful in the preparation of media for fast transport of selective species, including film membranes. | 05-12-2011 |
| 20110064685 | SILICONE REPLACEMENTS FOR PERSONAL CARE COMPOSITIONS - Described are personal care compositions, comprising an aqueous dispersion comprising a metallocene catalyzed polyolefin and an ethylene acrylic acid copolymer; a cationic polymer; and a least one cosmetically acceptable surfactant, emollient, or cosmetic active, provided that the personal care composition contains less than 0.09 wt % of silicone, and preferably is substantially free of silicone. | 03-17-2011 |
| 20110011616 | FLAME-RETARDANT POLYOLEFIN/THERMOPLASTIC POLYURETHANE COMPOSITION - The present invention is a flame-retardant polyolefin/thermoplastic polyurethane formulation made from or containing a polyolefin, a thermoplastic polyurethane, and an intumescent, polyphosphate flame retardant composition. The invented system achieves elongations> | 01-20-2011 |
| 20110009577 | ENHANCED CONDENSED MODE OPERATION IN METHOD OF PRODUCING POLYOFEFINS WITH CHROMIUM BASED CATALYSTS - A gas phase polymerization process for producing a polyethylene polymer including polymerizing ethylene and optionally at least one α-olefin comonomer in a fluidized bed reactor under condensed mode operating conditions using a Cr | 01-13-2011 |
| 20100331499 | RAW MATERIAL EFFICIENCY METHOD AND PROCESS - A method and apparatus are disclosed for controlling product discharge from a fluidized bed reactor and for minimizing the loss of the unreacted monomer in the fluidizing gas upon removing the solid polymer product from the reactor. The method and apparatus utilize at least one detector in the product tank or its vent line and a control system in communication with the detector and the product tank fill valve, along with certain algorithms, to adjust by an iterative process, the product discharge time, thereby maximizing resin fill in the product tank and minimizing the lost reactor gas volume. | 12-30-2010 |
| 20100144967 | METHODS OF CONTROLLING PROPERTIES IN MULTIMODAL SYSTEMS - The invention is directed to a polymerization system and method of controlling resin properties during the production of bimodal and multimodal polymer compositions using at least one manipulated variable to minimize dynamic deviations from polymer characteristics. In particular embodiments, the method of control includes determining a property of the resin based on a current and/or previous values or estimates or process variables or polymer characteristics. In this manner the control actions serve to reduce process upsets or facilitate in transitioning to a new product or grade to reduce the amount of off-grade resin material produced during transition or during steady state manufacture. | 06-10-2010 |
