  • Patent number: 8455592
    Abstract: 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.

  • Patent number: 8308886
    Abstract: 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.

  • Patent number: 8022152
    Abstract: 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.

  • Patent number: 7998895
    Abstract: 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.
