Patent number: 7056991Abstract: The present invention relates to propylene polymerization process in a bulk loop reactor, and particularly to propylene polymerization process for polymerizing commercial quantities of polypropylene in a bulk loop reactor by sequentially introducing Ziegler-Natta and metallocene catalyst systems into the bulk loop reactor.Type: GrantFiled: December 10, 2004Date of Patent: June 6, 2006Assignee: Fina Technology, Inc.Inventors: Ronald Tharappel, Renaud Oreins, William Gauthier, David Attoe, Kevin McGovern, Michel Messiaen, David Rauscher, Kai Hortmann, Michel Daumerie

Patent number: 7053163Abstract: The tendency of copolymer fluff grains of propylene and ethylene to agglomerate is reduced by injecting at least one olefin comonomer, such as ethylene monomer, into more than one point along the length of the reactor, rather than injecting all of the ethylene at one point. This process reduces the tendency of copolymer fluff grains to agglomerate and cause processing problems as compared with injecting the comonomer at only one point. Copolymer made by this process is expected to have lower substantially amorphous polypropylene content and better organoleptics than copolymer made where the ethylene is injected at only one point. In one non-limiting embodiment the copolymerization reactor is a loop-type reactor.Type: GrantFiled: February 22, 2005Date of Patent: May 30, 2006Assignee: Fina Technology, Inc.Inventors: Jun Tian, David Rauscher, William Gauthier, Mark C.
