MIXED PHOSPHINIMINE CATALYST |
摘要 |
A supported catalyst for the polymerization of olefins, especially ethylene, has at least two catalyst components having different propagation and/or termination constants. Each catalyst component must have at least one phosphinimine ligand. The polymer produced according to this invention has a broad molecular weight distribution. Catalysts according to this invention have a very surprising and desirable hydrogen response. |
