MODIFIED CHROMIUM-BASED CATALYSTS AND POLYMERIZATION PROCESSES FOR USING THE SAME
摘要
Embodiments disclosed herein generally relate to olefin polymerization catalysts, and more specifically to chromium-based catalysts and methods of use of chromium-based catalysts for the production of polyolefins, and even more specifically to methods for controlling or tailoring the flow index response of chromium-based catalysts through the controlled addition of a reducing agent to the catalysts under controlled mixing conditions.
