Patent number: 6060562Abstract: A thermoplastic composition with improved properties for making fuel containers, e.g. for fuel oil, petrol, diesel oil or alcohol, and specifically for making fuel lines for feeding fuel to a fuel tank or engine. The thermoplastic composition includes a thermoplastic polymer matrix and at least one compound that enhances the resilience of thermoplastic compositions. Said matrix consists of a mixture of: at least one first thermoplastic copolymer produced by copolymerising .epsilon.-caprolactam with at least one monomer selected from the group which includes an amino acid having at least nine carbon atoms, or the corresponding lactam, and a mixture of hexamethylediamine and a diacid having at least nine carbon atoms, the weight ratio of the .epsilon.-caprolactam to the total amount of hexamethylenediamine and diacid being 4-9; and at least one second thermoplastic polymer or copolymer produced by polymerising monomers having at least nine carbon atoms.Type: GrantFiled: June 5, 1998Date of Patent: May 9, 2000Assignee: Nyltech ItaliaInventors: Cesare Guaita, Franco Speroni

Patent number: 6054531Abstract: Weatherable thermoplastic compositions, such as a copolymer of styrene and acrylonitrile (SAN) are provided having improved impact strength. Improvements in thermoplastic composition properties are the result of the incorporation of the graft of an emulsion polymerized cross-linked poly(acrylate) rubber. The emulsion polymerized cross-linked poly(acrylate) rubber is synthesized in the presence of an effective amount of an alpha-alkylstyrenic monomer, such as alpha-methylstyrene dimer; the emulsion polymerized cross-linked poly(acrylate) rubber can be monomodal or bimodal.Type: GrantFiled: November 23, 1998Date of Patent: April 25, 2000Assignee: General Electric CompanyInventor: Daniel Horace Craig

Patent number: 6030551Abstract: A process for producing a conductive polyaniline is disclosed. The process includes mixing an aniline monomer, a water-immiscible organic solvent, at least one protonic acid doping agent and water together to form an emulsion via agitation, stopping agitation to allow the emulsion to separate into an aqueous phase and a non-aqueous phase, separating the non-aqueous phase from the aqueous phase, and adding an oxidation agent into the non-aqueous phase to carry out polymerization. A non-aqueous in-situ formed transparent polyaniline solution prepared by the process is also disclosed.Type: GrantFiled: April 7, 1999Date of Patent: February 29, 2000Assignee: Conpoly Technology Co., Ltd.Inventors: Ko-Shan Ho, Tar-Hwa Hsieh

Patent number: 6031023Abstract: Novel white board dry erase ink compositions are provided which are comprised of poly(oxyalkylene) substituted colorants, volatile solvent vehicles, and binder resins. The binder resin is insoluble within the alcohol of the volatile vehicle; however, the degree of alkoxylation on the colorant aids in solubilizing the binder resin within the entire solution. Once the composition is transferred to a white board, the solvent evaporates, leaving the binder resin and colorant as a friable discontinuous film which is easily removed from the writing surface. The inventive composition has improved erasability, writability, stability within the marker stylus, and washability from skin and fabrics. Markers and methods of producing the ink composition are also provided.Type: GrantFiled: December 3, 1997Date of Patent: February 29, 2000Assignee: Milliken & CompanyInventors: Clifford C. Carroll, Michael A. Valenti
