CONTROLLING RESIN PROPERTIES IN A GAS PHASE POLYMERIZATION PROCESS |
摘要 |
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. |
