| 20090036640 | Oligomer Removing Agent for Polyester-Based Fiber Material - An oligomer removing agent for polyester-based fiber materials comprises a polyester copolymer which is obtained by polycondensation of a dibasic acid component containing 15-65 mol % of a sulfonate group-containing dibasic acid and a dihydric alcohol component containing polyethylene glycol with a molecular weight of 900-3500, and which has a 200° C. melt viscosity of 5000-23,000 mPa·s and has 10-40 mass % polyoxyethylene chains in the molecule. The oligomer removing agent is able to overcome the problems caused by deposition of polyester oligomers, when added to the dyeing bath in a dyeing step for polyester fiber materials or for fiber materials that are composites thereof with other fiber materials. | 02-05-2009 |
| 20130289233 | REVERSIBLE CROSSLINKED POLYMERS - The present invention provides reversibly crosslinked polymers and methods for producing and using the same. In particular, reversibly crosslinked polymers of the invention comprise polyesters comprising thiol groups as crosslinking moieties. Oxidation of thiol groups affords crosslinked polymer comprising a disulfide linkage and reduction of the disulfide linkage provides non-crosslinked polymer. In some embodiments, polymers of the invention are degradable and are biocompatible. | 10-31-2013 |

| 20140039150 | PHOTOPOLYMERIZABLE COMPOSITIONS FOR SOLVENTLESS FIBER SPINNING - Disclosed are methods of fiber spinning and polymer fibers that utilize multifunctional thiol and enes compounds. Also, the subject matter disclosed herein relates to uses of polymer fibers and articles prepared from such fibers. | 02-06-2014 |
| 528295000 | Sulfur-containing aryl compound | 5 |
| 20090036641 | Anionic Soil Release Polymers - Anionic soil release polyesters are described which consist of terephthalic acid, sulfoisophthalic acid-(poly)alkylene glycol, a non-ionic end group and optionally a polyfunctional crosslinking monomer. These polyesters are suitable as soil release components in washing and cleaning compositions. | 02-05-2009 |
| 20090131628 | NORMAL-PRESSURE CATION-DYEABLE POLYESTER, TEXTILE PRODUCT MADE FROM THE SAME, AND PRODUCTION METHOD FOR THE SAME - A normal-pressure cation-dyeable polyester is provided which contains an isophthalic acid component having a metal sulfonate group in a predetermined proportion based on the total of acid components present in the polyester, and contains a polyalkylene glycol having an average molecular weight of 150 to 600 in a predetermined proportion based on the polyester, wherein the proportion of diethylene glycol based on the total of glycol components and a terminal carboxyl group concentration are each set within a predetermined range. The polyester is stable in quality and excellent in dark- and pale-color light fastness when used for textile products. | 05-21-2009 |

| 20140031511 | CONTINUOUS POLYMERIZATION PROCESS USING INTENSELY STIRRED VESSELS - A continuous polymerization process where one or more stirred vessels (intermittent reactor vessels) are employed in oligomer transfer line for mixing additives. An additive is added in the stirred vessel either as a solution or as slurry. The additive may or may not be reactive with the other monomer of the polyester molecule. The additive reacts with the monomer and incorporates in the polymer backbone in one of the embodiment. One or more further additives are mixed with the pre-reactor monomer mix and are charged in the first reactor or charged through the stirred vessel in the form of single slurry or solution or multiple slurries or solutions. Any further vessels employed provide higher residence time proportionate to output and use of such vessels in reactor system is independent of the any further additives. | 01-30-2014 |
| 20140058059 | POLYESTER WITH EXCELLENT THERMOSTABILITY AND MANUFACTURING METHOD THEREFOR - A polyester has excellent thermostability with only a small reduction in intrinsic viscosity during melt molding. The polyester is obtained from a dicarboxylic acid, and/or an ester-forming derivative thereof, and a diol which contains 15 to 500 ppm of a 1,2-propanediol-derived component. | 02-27-2014 |
