| 20080226856 | Polyester Resins and Polyester Containers Having Reduced Frictional Properties - The invention embraces polyester resins and containers that include surface-modified talc. The invention also embraces a method for the late introduction of surface-modified talc via a reactive carrier to achieve a polyester resin that is capable of being formed into low-haze, high-clarity bottles possessing reduced coefficient of friction. | 09-18-2008 |
| 20080274317 | Polyester Resins for High-Efficiency Injection Molding - The present invention relates to titanium-catalyzed polyethylene terephthalate resins that are capable of being formed into articles (e.g., carbonated soft drink and water bottle preforms) at reduced injection-molding cycle times. In particular, the titanium-catalyzed polyethylene terephthalate resins of the present invention can be formed into carbonated soft drink bottle preforms at reduced injection-molding cycle times to yield high-clarity, carbonated soft drink bottles that possess satisfactory resistance to stress cracking and thermal creep. | 11-06-2008 |
| 20090176046 | Polyester Resins for High-Strength Articles - The present invention relates to slow-crystallizing, titanium-catalyzed polyethylene terephthalate resins that are useful for making high-strength, high-clarity bottles that possess improved resistance to stress cracking and thermal creep. The polyethylene terephthalate resins possess improved reheating profiles and are especially useful for making polyester articles that have exceptional clarity, dimensional stability, and thermal stability. | 07-09-2009 |
| 20090187002 | Composite Solid Phase Polymerization Catalyst - The invention is a method for making condensation polymers, such as polyethylene terephthalate polyester. The method includes introducing to a polycondensation reaction a catalyst system that includes a coordination catalyst and a composite catalyst, which includes an acid component and an auxiliary component. | 07-23-2009 |
| 20090198022 | Solid Phase Polymerization Catalyst System - The invention is a method for making condensation polymers, such as polyethylene terephthalate polyester. The method includes introducing a catalyst system, which includes a coordination catalyst component and an acid component, to a polycondensation reaction. | 08-06-2009 |
| 20090306313 | Titanium-Nitride Catalyzed Polyester - The present invention relates to methods for making polyethylene terephthalate resin in which a titanium-nitride polycondensation catalyst is introduced prior to or during the initial stages of esterification or transesterification. | 12-10-2009 |
| 20100221472 | Polyester Resins for High-Strength Articles - The present invention relates to slow-crystallizing, titanium-catalyzed polyethylene terephthalate resins that are useful for making high-strength, high-clarity bottles that possess improved resistance to stress cracking and thermal creep. The polyethylene terephthalate resins possess improved reheating profiles and are especially useful for making polyester articles that have exceptional clarity, dimensional stability, and thermal stability. | 09-02-2010 |
| 20110212282 | Polyester Resins for High-Strength Articles - The present invention relates to slow-crystallizing, titanium-catalyzed polyethylene terephthalate resins that are useful for making high-strength, high-clarity bottles that possess improved resistance to stress cracking and thermal creep. The polyethylene terephthalate resins possess improved reheating profiles and are especially useful for making polyester articles that have exceptional clarity, dimensional stability, and thermal stability. | 09-01-2011 |
