Patent number: 8455592Abstract: Disclosed is a polycondensation process for preparing block copolyesters comprising blocks of fluoroether functionalized aromatic polyester and blocks of unmodified polyester. According to the process, a non-fluorinated poly(alkylene arylate) first homopolymer and a fluoroether functionalized poly(alkylene arylate) second homopolymer are combined to form a reaction mixture; the reaction mixture is heated to a temperature above the melting temperatures of each said homopolymer to prepare a molten reaction mixture; and the reaction is continued until the desired molecular weight is achieved. The block copolymers incorporated into blends with unmodified aromatic polyester impart oil and soil resistance to shaped articles prepared from the blends.Type: GrantFiled: November 8, 2011Date of Patent: June 4, 2013Assignee: E I du Pont de Nemours and CompanyInventors: Neville Everton Drysdale, Elizabeth Forrester Mccord, Fredrik Nederberg

Patent number: 8308886Abstract: The invention discloses processes for thermal transfer patterning of a nanoparticle layer and a corresponding proximate portion of a carrier layer, and optionally additional transfer layers, together onto a thermal imaging receiver. The invention is useful for dry fabrication of electronic devices. Additional embodiments of the invention include multilayer thermal imaging donors comprising in layered sequence: a base film, a carrier layer and a nanoparticle layer. The carrier layer can be a dielectric or conducting layer. When the carrier layer is a dielectric layer, the base film includes a light attenuating agent in the form of a dye or pigment.Type: GrantFiled: July 17, 2006Date of Patent: November 13, 2012Assignee: E I du Pont de Nemours and CompanyInventors: Gerald Donald Andrews, Marc B Goldfinger, Mark Andrew Harmer, Gary Delmar Jaycox, Lynda Kaye Johnson, Irina Malajovich, William J Marshall, Elizabeth Forrester McCord, Charles Nehemiah McEwen, Jeffrey Scott Meth, Richard Kevin Bailey, Geoffrey Nunes, Rinaldo Soria Schiffino, Paul J Shannon, Kenneth George Sharp, Karyn B Visscher, Graciela Beatriz Blanchet, John W Catron, Jr., Reid John Chesterfield, Thomas C Felder, Feng Gao, Howard David Glicksman

Patent number: 8022152Abstract: Ethylene and allyl- or vinylsilanes are efficiently copolymerized by certain late transition metal complexes containing selected bidentate or tridentate ligands. The resulting novel polymers may be crosslinked by moisture when vinylsilane contains groups bound to silicon which are hydrolyzable. The polymers are useful for wire coating, crosslinked foams, pipes, and other uses.Type: GrantFiled: December 19, 2007Date of Patent: September 20, 2011Assignee: E.I. du Pont de Nemours and CompanyInventors: Steven Dale Ittel, Lynda Kaye Johnson, Lin Wang, Ying Wang, Elizabeth Forrester McCord, Catherine E.

Patent number: 7998895Abstract: Transition metal complexes of selected monoanionic phosphine ligands, which also contain a selected Group 15 or 16 (IUPAC) element and which are coordinated to a Group 3 to 11 (IUPAC) transition metal or a lanthanide metal, are polymerization catalysts for the (co)polymerization of olefins such as ethylene and ?-olefins, and the copolymerization of such olefins with polar group-containing olefins. These and other nickel complexes of neutral and monoanionic bidentate ligands copolymerize ethylene and polar comonomers, especially acrylates, at relatively high ethylene pressures and surprisingly high temperatures, and give good incorporation of the polar comonomers and good polymer productivity. These copolymers are often unique structures, which are described.Type: GrantFiled: August 1, 2008Date of Patent: August 16, 2011Assignee: E.I. du Pont de Nemours and CompanyInventors: Lin Wang, Elisabeth M.
