Patent number: 7511081Abstract: The present invention relates to a recycling method of a mixed waste of polyester and polyamide (hereinafter, referred to as “mixed waste”) in which polyesters including polyethylene terephthalate and polyamides are inseparable from one another. In accordance with the recycling method of the present invention, it is possible to prepare a solid block polymer having an acid value of 1 to 150 mgKOH/g, a weight average molecular weight of 3,000 to 50,000 and a softening point of 10 to 150° C., or a liquid polyester-amide block polymer composition having good compatibility, solubility and dispersibility. In addition, the polymer having an acid value of more than 20 mgKOH/g is reacted with a basic compound to form a neutralized salt which is then used to prepare a water-soluble polyester-amide block polymer composition.Type: GrantFiled: March 24, 2005Date of Patent: March 31, 2009Inventors: Do-Gyun Kim, Hyo-Sung Kim

Patent number: 7332253Abstract: A radiation-sensitive composition and negative-working imageable element includes a polymeric binder comprising pendant allyl ester groups to provide solvent resistance, excellent digital speed (sensitivity) and can be imaged and developed without a preheat step to provide lithographic printing plates. The polymeric binder can be prepared with a precursor polymer having pendant carboxy groups that are converted to allyl ester groups using an allyl-containing halide in the presence of a base in order to avoid gelation.Type: GrantFiled: July 27, 2006Date of Patent: February 19, 2008Assignee: Eastman Kodak CompanyInventors: Ting Tao, Scott A. Beckley

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 -
