20110282018 | PROCESS FOR SELECTIVELY POLYMERIZING ETHYLENE AND CATALYST THEREFOR - The present invention generally relates to a process that selectively polymerizes ethylene in the presence of an alpha-olefin, and to a metal-ligand complex (precatalyst) and catalyst useful in such processes, and to related compositions. The present invention also generally relates to ligands and intermediates useful for preparing the metal-ligand complex and to processes of their preparation. | 11-17-2011 |
20120108770 | HIGH TEMPERATURE POLYETHYLENE SOLUTION POLYMERIZATION PROCESS - Metal complexes of polyvalent aryloxyethers appropriately substituted with sterically bulky substituents possess enhanced solubility in aliphatic and cycloaliphatic hydrocarbons and/or when employed as catalyst components for the polymerization of ethylene/α-olefin copolymers, produce products having reduced I | 05-03-2012 |
20130144018 | PROCESS FOR POLYMERIZING A POLYMERIZABLE OLEFIN AND CATALYST THEREFOR - The present invention generally relates to a process that copolymerizes two or more polymerizable olefins, and to cataclyst comprising a metal-ligand complex (precatalyst). The present invention also generally relates to ligands useful for preparing the metal-ligand complex. | 06-06-2013 |
20140163186 | PROCESS FOR SELECTIVELY POLYMERIZING ETHYLENE AND CATALYST THEREFOR - The present invention generally relates to a process that selectively polymerizes ethylene in the presence of an alpha-olefin, and to a metal-ligand complex (precatalyst) and catalyst useful in such processes, and to related compositions. The present invention also generally relates to ligands and intermediates useful for preparing the metal-ligand complex and to processes of their preparation. | 06-12-2014 |
20140357918 | PROCESS FOR PRODUCING LOW MOLECULAR WEIGHT ETHYLENE- AND ALPHA-OLEFIN-BASED MATERIALS - The present invention generally relates to a process that prepares polyethylenes, poly-α-olefins or poly(co-ethylene-?-olefin) having backbone weight average molecular weights less than 2500 daltons. The process uses a metal-ligand complex as a precatalyst and can be carried out at temperatures ranging from 30° C. to 300° C. The relatively low molecular weight of the products enables improved viscosity control for a wide variety of applications. | 12-04-2014 |
