| 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 |
