Patent number: 7678726Abstract: A supported polymerization catalyst system is prepared by a method comprising the following steps: (i) addition of a cocatalyst to a porous support, (ii) mixing a polymerisation catalyst with a polymerisable monomer, and (iii) contacting together the components resulting from steps (i) and (ii). The porous support is preferably silica and the polymerisation catalyst is preferably a metallocene. The polymerisable monomer is typically 1-hexene and the supported catalyst system provides advantages a slowly decaying activity profile particularly when operating in the gas phase.Type: GrantFiled: August 4, 2004Date of Patent: March 16, 2010Assignee: Innovene Europe LimitedInventors: Grant B.

Patent number: 7645835Abstract: Blend compositions containing a novel homopolymer, the use of which allows the incorporation of more comonomer in the additional components of the blend (for the same overall density) resulting in increased tie molecule formation and improvement in properties such as ESCR, toughness and impact strength are disclosed. The homopolymers are important for applications where a high density is needed to ensure certain mechanical properties like abrasion resistance, indentation resistance, pressure resistance, topload resistance, modulus of elasticity, or morphology (for the chlorination of PE to CPE) and additional advantages such as melt processability. The blend can be obtained by dry or melt mixing the already produced components, or through in-situ production by in parallel and/or in series arranged reactors. These resins can be used in applications such as films, blow molded, injection molded, and rotomolded articles, fibers, and cable and wire coatings and jacketings and, various forms of pipe.Type: GrantFiled: June 21, 2006Date of Patent: January 12, 2010Assignee: Dow Global Technologies, Inc.Inventors: Jozef J.
