Articles that can be made from the sulfonated aromatic copolyesters include films, coatings and laminates. Some of the compositions and articles are biocompostable. The films can further be used to form shaped articles such as sheets, food packaging such as sandwich wraps, thermoformed containers, and coatings for, for example, films and other substrates. The sulfonated aromatic copolyesters contain a hydroxyalkanoic acid component.Type: GrantFiled: July 9, 2004Date of Patent: April 15, 2008Assignee: E. I. du Pont de Nemours and CompanyInventor: Richard Allen Hayes

Method for incorporating nitrogen containing methine light absorbers in pet and compositions thereof
Patent number: 7282555Abstract: The present invention is a method for efficiently incorporating a nitrogen containing methine light absorber into a polyester resin. The method includes forming a reaction mixture comprising combining a diol component, a diacid component selected from the group consisting of dicarboxylic acids, dicarboxylic acid derivatives, and mixtures thereof, an antimony containing compound, a phosphorus containing compound, a metal containing compound, and a nitrogen containing methine light absorber. The reaction mixture is polymerized in a polycondensation reaction system. In another embodiment the light absorber is added while the reaction products of one reactor are being transferred to the next reactor in the polycondensation reaction system. The present invention is also directed articles made from the polyester resin.Type: GrantFiled: May 27, 2004Date of Patent: October 16, 2007Assignee: Eastman Chemical CompanyInventors: Max Allen Weaver, Jason Clay Pearson, Dale Milton Blakely, Frederick Leslie Colhoun -
Patent number: 7235623Abstract: Polyester compositions that provide a higher throughput in calendering processes may be prepared from a polyester having crystallization half time of at least 5 minutes, an inherent viscosity of about 0.55 to about 0.75 dL/g, a branching monomer, and a release additive. The polyester compositions show a combination of excellent melt strength with good shear response that permits higher calendering line speeds before melt fracture occurs. Also disclosed are processes for film or sheet by calendering the above compositions and the film or sheet produced therefrom. The polyester compositions, film, or sheet also may include plasticizers and/or flame retardants to increase their flexibility and enable their use in commercial applications requiring flame resistance. The film and sheet have excellent appearance and can be used in a wide range of decorative and packaging applications.Type: GrantFiled: November 26, 2003Date of Patent: June 26, 2007Assignee: Eastman Chemical CompanyInventors: Marc Alan Strand, Rodney Layne Piner, Eric Jon Moskala

Patent number: 7211634Abstract: Disclosed is a process for the preparation of high molecular weight polyesters by reacting one or more dicarboxylic acids directly with 1,4-cyclohexanedimethanol and, optionally, one or more diols. The process uses an overall diol to dicarboxylic acid molar ratio of about 0.97 to about 1.2 and an incremental addition of either the diacid or diol components. The process provides a shorter total reaction time and, thus, lessens the thermal degradation of polyester which may result in high color and reduced molecular weight.Type: GrantFiled: April 28, 2006Date of Patent: May 1, 2007Assignee: Eastman Chemical CompanyInventors: Daniel Lee Martin, Joseph Franklin Knight, Benjamin Fredrick Barton, Damon Bryan Shackelford
