ABSTRACT:
Olefins are polymerized with a catalyst which forms on mixing a supported chromium oxide composite and a silane adjuvant. This system allows the production of polymer of a given melt index at a higher temperature, thus increasing the production rate and is of particular utility in solution polymerizations designed to produce ethylene polymers and copolymers.
