In syntheses, an olefin of 2-20 carbon atoms is polymerized in the presence of a catalyst comprising a transition metal compound represented by the formula LmMXn wherein M is a transition metal atom of Group 3-11, m is 1-5, n is a number satisfying a valence of M, L is a ligand—coordinated to the central metal M—which contains a heteroatom having no direct bond to the central metal, and X is e.g. halogen or a hydrocarbon.Type: GrantFiled: December 1, 2008Date of Patent: December 25, 2012Assignee: Mitsui Chemicals, Inc.Inventors: Makoto Mitani, Yasunori Yoshida, Junichi Mohri, Kazutaka Tsuru, Seiichi Ishii, Shinichi Kojoh, Tomoaki Matsugi, Junji Saito, Naoto Matsukawa, Shigekazu Matsui, Takashi Nakano, Hidetsugu Tanaka, Norio Kashiwa, Terunori Fujita

Patent number: 8324337Abstract: A catalyst, co-catalyst, and/or chain transfer agent is added at a time after initiation of an addition polymerization reaction to produce a polymer product with a widened molecular weight distribution relative to having all of the components in the original reaction mixture. The catalyst, co-catalyst, or chain transfer agent may be added discretely or continuously to the reaction to produce a product with a bimodal, trimodal, or other broadened molecular weight distribution.Type: GrantFiled: November 17, 2010Date of Patent: December 4, 2012Assignee: Novomer Inc.Inventor: Scott D. Allen

Patent number: 8318872Abstract: A method of performing a polymerization reaction in a gas phase polymerization reactor to produce a bimodal polymer while controlling activity of a bimodal polymerization catalyst composition in the reactor by controlling concentration of at least one induced condensing agent (‘ICA’) in the reactor is provided. In some embodiments, the ICA is isopentane (or another hydrocarbon compound) and the bimodal catalyst composition includes a Group 15 and metal containing catalyst compound (or other HMW catalyst for catalyzing polymerization of a high molecular weight fraction of the product), and a metallocene catalyst compound (or other LMW catalyst for catalyzing polymerization of a low molecular weight fraction of the product).Type: GrantFiled: December 17, 2008Date of Patent: November 27, 2012Assignee: Univation Technologies, LLCInventors: Bruce J. Savatsky, John H. Oskam, Mark W. Blood, Mark B. Davis, Douglas H. Jackson, Timothy R. Lynn, Daniel P. Zilker, Jr.
