20110288248 | Reduced reactor fouling - Fouling in a dispersed phase reactor in the presence of a phosphinimine catalyst and MAO may be reduced by reducing the loading of the phosphinimine catalyst to provide from 0.02 to 0.031 mmol of transition M per g of catalyst while still maintaining a productivity of not less than 2500 g of polymer/gram of catalyst. The catalyst may optionally be used in the presence of an antistatic agent. | 11-24-2011 |
20120238720 | POLYETHYLENE FILM - Polyethylene films having a good balance of optical and mechanical properties are disclosed. The films are derived from ethylene copolymer compositions made with a suitably substituted phosphinimine catalyst. The ethylene copolymers have very narrow molecular weight distributions and broadened comonomer distributions. | 09-20-2012 |
20120316297 | Modified phosphinimine catalysts for olefin polymerization - Olefin polymerization is carried out with a supported phosphinimine catalyst which has been treated with a long chain substituted amine compound. | 12-13-2012 |
20120316301 | Methods for controlling ethylene copolymer properties - A method for altering the polymer architecture of ethylene copolymers made with a supported phosphinimine polymerization catalyst. The method involves changing the amount of a catalyst modifier added to a reactor separately from or together with a supported phosphinimine polymerization catalyst. | 12-13-2012 |
20130053524 | Feeding Highly Active Phosphinimine Catalysts to a Gas phase reactor - A highly active, supported phosphinimine catalyst is fed to a gas phase reactor as a slurry in a liquid hydrocarbon. Feeding the catalyst to a gas phase reactor in a viscous liquid hydrocarbon modifies catalyst initiation kinetics. | 02-28-2013 |
20140357817 | MODIFIED PHOSPHINIMINE CATALYSTS FOR OLEFIN POLYMERIZATION - Olefin polymerization is carried out with a supported phosphinimine catalyst which has been treated with a long chain substituted amine compound. | 12-04-2014 |
20140378632 | MODIFIED PHOSPHINIMINE CATALYSTS FOR OLEFIN POLYMERIZATION - Olefin polymerization is carried out with a supported phosphinimine catalyst which has been treated with a long chain substituted amine compound. | 12-25-2014 |
20150099856 | MODIFIED PHOSPHINIMINE CATALYSTS FOR OLEFIN POLYMERIZATION - Olefin polymerization is carried out with a supported phosphinimine catalyst which has been treated with a long chain substituted amine compound. | 04-09-2015 |
