| 20100152329 | POLY(TRIMETHYLENE TEREPHTHALATE) POLYMER BLENDS THAT HAVE REDUCED WHITENING - The present invention relates to a composition being poly(trimethylene terephthalate) and at least one blend polymer. The invention further includes a process of producing reduced-whitening in articles made from the poly(trimethylene terephthalate) and at least one blend polymer. | 06-17-2010 |
| 20100152411 | POLY(TRIMETHYLENE TEREPHTHALATE) WITH REDUCED WHITENING - The present invention relates to a process for making a non-whitening poly(trimethylene terephthalate)-based polymer, wherein the polymer is melt polymerized 1,3-propanediol and a terephthalate component in the presence of a co-monomer, wherein the poly(trimethylene terephthalate)-based polymer comprises a PTT cyclic dimer level below 2 wt. %. | 06-17-2010 |
| 20100152412 | REDUCTION OF WHITENING OF POLY(TRIMETHYLENE TEREPHTHALATE) PARTS BY SOLVENT EXPOSURE - This invention relates to a process for producing non-whitening molded parts of poly(trimethylene terephthalate) (PTT) with reduced whitening after an elevated temperature aging test by exposing the parts to solvents. | 06-17-2010 |
| 20100227182 | THERMOPLASTIC MOLDED VEHICLE LIGHT BEZEL - Disclosed is a thermoplastic molded vehicle light bezel including a polyester molding resin comprising a thermoplastic polyester selected from the group consisting of poly(butylene terephthalate) homopolymer, poly(butylene terephthalate) copolymer, poly(trimethylene terephthalate) homopolymer, poly(trimethylene terephthalate) copolymer and blends thereof, and sodium montanate. | 09-09-2010 |
| 20100227183 | THERMOPLASTIC MOLDED ARTICLE HAVING A METAL LAYER - Disclosed is a thermoplastic molded article having at least one surface having a metal layer, wherein the article includes a poly(trimethylene terephthalate) molding resin having a cyclic dimer content of less than or equal to 1.1 wt %, as determined with nuclear magnetic resonance analysis, based on the weight of said poly(trimethylene terephthalate) repeat units and said cyclic dimer; and an intrinsic viscosity of 0.9 to about 2.0 dL/g. Preferably the metal layer is aluminum. Molded parts include vehicle light bezels including headlight, taillight, direction light bezels, and vehicle interior light bezels. | 09-09-2010 |
| 20100227960 | PROCESS OF MAKING A POLY(TRIMETHYLENE TEREPHTHALATE) RESIN HAVING LOW CYCLIC DIMER CONTENT, AND COMPOSITIONS AND ARTICLES THEREFROM - A process for making a high viscosity poly(trimethylene terephthalate) (PTT) resin having a low cyclic dimer content of less than or equal to 1.1 wt % as determined with nuclear magnetic resonance analysis and an intrinsic viscosity in the range of 0.9 to 2.0 dL/g; the PTT resin composition provided by the process; and molded articles derived from the composition are disclosed. | 09-09-2010 |
| 20100227999 | REDUCTION OF WHITENING OF POLYMER PARTS - This invention relates to a process for producing non-whitening molded articles of poly(trimethylene terephthalate) (PTT) with reduced whitening by treating the articles with heat. | 09-09-2010 |
| 20110311759 | FLAME RETARDANT PERFORMANCE IN POLY (TRIMETHYLENE) TEREPHTHALATE - Poly(trimethylene terephthalate) compositions, and articles made therefrom, having improved flame retardancy are provided. The compositions can be used to make carpets that are suitable for installation where flame retardancy is desired. | 12-22-2011 |
