Patent number: 9902790Abstract: A method of polymerizing olefins is disclosed. The method comprises contacting ethylene and at least one comonomer with a catalyst system to produce a polyolefin polymer that is multimodal. The catalyst system comprises a first catalyst that promotes polymerization of the ethylene into a low molecular weight (LMW) portion of the polyolefin polymer and a second catalyst that promotes polymerization of the ethylene into a high molecular weight (HMW) portion of the polyolefin polymer. The first catalyst and at least a portion of the second catalyst are co-supported to form a commonly-supported catalyst system and at least a portion of the second catalyst is added as a catalyst trim feed to the catalyst system.Type: GrantFiled: February 10, 2015Date of Patent: February 27, 2018Assignee: Univation Technologies, LLCInventors: Daniel D. Vanderlende, C. Jeff Harlan, Haiqing Peng, Michael D. Awe, Roger L. Kuhlman, Ching-Tai Lue, Timothy R. Lynn, Wesley R. Mariott, Daniel P. Zilker, Jr.
