Patent number: 6495638Abstract: A process is provided to produce a catalyst system. The process comprises blending a first component and a second component. The first component of the catalyst system comprises chromium on a support. The amount of chromium on the support is from about 0.05 to about 5 weight percent based on the weight of the support. The support comprises fluorided alumina. The support has a surface area from about 200 to about 550 square meters per gram and a pore volume from about 0.7 to about 2.5 cubic centimeters per gram. The first component is activated at a temperature in the range of about 500° C. to about 900° C. The second component is a transition metal halide catalyst. A process comprising polymerizing ethylene or copolymerizing ethylene and at least one other monomer using the catalyst system to produce ethylene polymers is also provided.Type: GrantFiled: December 30, 1998Date of Patent: December 17, 2002Assignee: Phillips Petroleum CompanyInventors: Max P.

Publication number: 20020061986Abstract: The present invention provides an olefin/cycloolefin/alkylstyrene copolymer which is non-functionalized, functionalized, or grafted. By the functionalization of the benzylic protons of the alkylstyrene unit, the copolymer can be functionalized. The functionalized or grafted olefin/cycloolefin/alkylstyrene copolymer has good adhesion to a substrate and good compatibility with other polymers compared with the non-functionalized copolymer.Type: ApplicationFiled: December 28, 2001Publication date: May 23, 2002Applicant: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Shu-Hua Chan, Chi-Lan Li, Ching Ting, Joung-Yei Frank Chen
