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 |
20120190858 | PROCESS FOR THE PREPARATION OF 4-AMINO-3-CHLORO-5-FLUORO-6-(SUBSTITUTED) PICOLINATES - 4-Amino-3-chloro-5-fluoro-6-(substituted)picolinates are conveniently prepared from 3,4,5,6-tetrachloropicolinonitrile by a series of steps involving fluorine exchange, amination, reaction with hydrazine, halogenation, hydrolysis and esterification, and transition metal assisted coupling. | 07-26-2012 |
20130090431 | STORAGE-STABLE HEAT-ACTIVATED TERTIARY AMINE CATALYSTS FOR EPOXY RESINS - Epoxy adhesive compositions contain a heat-activatable catalyst. The heat-activatable catalyst includes a tertiary amine catalyst and a novolac resin that has a weight average molecular weight of at least 3000. One-component epoxy adhesive formulations that contain the heat-activatable catalyst have unexpectedly good storage stability. | 04-11-2013 |
20130131289 | SELF LIMITING CATALYST COMPOSITION FOR ETHYLENE POLYMERIZATION - A process for polymerizing ethylene to produce an ethylene-based polymer including contacting ethylene with a Ziegler-Natta procatalyst, an alkylaluminum cocatalyst and a self limiting agent selected from the group of aliphatic, cycloaliphatic, substituted cycloaliphatic or aromatic esters, anhydrides and amides such that the self limiting agent reduces polymerization rates to no greater than 40% of the polymerization rate in the absence of the self limiting agent at temperatures equal to or greater than 120° C. is provided. | 05-23-2013 |
