Patent number: 7999039Abstract: A process of making a polymer is described. The process includes contacting one or more olefinic monomers in the presence of at least a high molecular weight (HMW) catalyst and at least a low molecular weight (LMW) catalyst in a polymerization reactor system; and effectuating the polymerization of the one or more olefinic monomers in the polymerization reactor system to obtain an olefin polymer, wherein the LMW catalyst has an RvL, defined as R v L = [ vinyl ] [ vinyl ] + [ vinylidene ] + [ cis ] + [ trans ] wherein [vinyl] is the concentration of vinyl groups in the olefin polymer produced by the low molecular weight catalyst expressed in vinyls/1,000 carbon atoms; [vinylidene], [cis] and [trans] are the concentration of vinylidene, cis and trans groups in the olefin polymer expressed in the number of the respective groups per 1,000 carbon atoms, of greater than 0.12, and wherein the HMW catalyst has a reactivity ratio, r1 of about 5 or less.Type: GrantFiled: August 16, 2004Date of Patent: August 16, 2011Assignee: Dow Global Technologies LLCInventors: Alexander W.

Publication number: 20060281866Abstract: A composition is disclosed which is particularly suited for use in extrusion coating. The composition comprises a polymeric material having a rheology such that the slope S of a natural log-natural log plot of loss modulus (or G?) versus storage modulus (or G?) is greater than [0.635*(melt index)+13.2]/[(melt index)+16.6], and wherein the polymeric material has a CDF RI fraction less than 0.23 of a GPC chromatogram which has a molecular weight above 85,000 g/mol, and a CDF LS fraction of more than 0.07 at a conventional GPC molecular weight of 1,750,000 g/mol or greater. The compositions exhibit reduced neck-in when used in extrusion coating and the neck-in is independent of melt strength, thereby facilitating improved extrusion processes.Type: ApplicationFiled: September 3, 2004Publication date: December 14, 2006Inventors: Thomas Oswald, James Cooper, Jeffrey Weinhold, David Gilluspie
