20130066022 | SHAPED HIGH MOLECULAR WEIGHT POLYETHYLENE ARTICLES, THEIR PRODUCTION AND USE - A shaped article, suitable for in a prosthetic device, is formed of polyethylene having a molecular weight of at least 3×105 g/mol as determined by ASTM 4020, and has a yield strength greater than 20 as determined by DIN EN ISO 527. The polyethylene is produced by polymerizing ethylene in the presence of a catalyst composition comprising a Group 4 metal complex of a phenolate ether ligand. | 03-14-2013 |
20130071663 | ULTRA-HIGH MOLECULAR WEIGHT POLYETHYLENE, ITS PRODUCTION AND USE - Ultra-high molecular weight polyethylene has a molecular weight greater than 20×106 gm/mol as determined by ASTM 4020 or by size exclusion chromatography (SEC) and is produced by polymerizing ethylene with a catalyst composition comprising a Group 4 metal complex of a phenolate ether ligand. | 03-21-2013 |
20130072649 | PROCESS FOR PRODUCING HIGH MOLECULAR WEIGHT POLYETHYLENE - In a process for producing high molecular weight polyethylene, ethylene is contacted with a slurry of a catalyst composition comprising a Group 4 metal complex of a phenolate ether ligand under polymerization conditions comprising a temperature of about 20° C. to less than 90° C. and a pressure of about 4 bar to about 40 bar. | 03-21-2013 |
20130079483 | HIGH MOLECULAR WEIGHT POLYETHYLENE FIBERS AND MEMBRANES, THEIR PRODUCTION AND USE - In a process for producing an elongated polyethylene component, such as a fiber or membrane, polyethylene powder having a molecular weight of at least 3×10 | 03-28-2013 |
20130090400 | PROCESS FOR PRODUCING HIGH MOLECULAR WEIGHT POLYETHYLENE - In a process for producing polyethylene having a molecular weight of at least 1×10 | 04-11-2013 |
20130090430 | PROCESS FOR PRODUCING HIGH MOLECULAR WEIGHT POLYETHYLENE - In a process for producing polyethylene having a molecular weight of at least 3×105 g/mol as determined by ASTM 4020, ethylene is contacted under polymerization conditions with a slurry of a catalyst composition in at least one hydrocarbon. The catalyst composition comprises a Group 4 metal complex of a phenolate ether ligand and the slurry includes from about 5 to less than 40 ppm per liter of a compound effective to increase the conductivity of said at least one hydrocarbon. | 04-11-2013 |
20130090438 | PROCESS FOR PRODUCING HIGH MOLECULAR WEIGHT POLYETHYLENE - In a process for producing polyethylene having a molecular weight of at least 3×10 | 04-11-2013 |
20140329921 | PROCESS FOR PRODUCING HIGH MOLECULAR WEIGHT POLYETHYLENE - In a process for producing polyethylene, ethylene is contacted under polymerization conditions with a slurry of a catalyst composition comprising a particulate support and a Group 4 metal complex of a phenolate ether ligand carried by the support and present in an amount so as to provide about 0.1 to about 35 μιηo | 11-06-2014 |
