Slurry polymerization using unsupported phosphinimine catalyst.

摘要

A slurry polymerization process uses an unsupported catalyst component which is an organometallic complex having a phosphinimine ligand and a cyclopentadienyl-type ligand. The use of the unsupported catalyst component allows simple, inexpensive catalyst addition techniques to be used in a slurry polymerization process. The catalyst component is highly active for ethylene (co)polymerization in the process of this invention.
