A polymerization process for stable gas phase reactor start-up when making ethylene copolymers having relatively high molecular weight distribution and melt flow ratio.

Process for polymerization in a fluidized bed reactor

Olefin polymerization is carried out with a supported phosphinimine catalyst which has been treated with a long chain substituted amine compound.

Modified phosphinimine catalysts for olefin polymerization

Methods for dramatically altering the processability of ethylene copolymers made with a supported phosphinimine polymerization catalyst. The method involves changing the polymerization reactor temperature during the polymerization of ethylene and a least one alpha-olefin when a phosphinimine catalyst which comprises a substituted or unsubstituted indenyl ligand and a phosphinimine type ligand.
