| 20090005531 | Solid state polymerization process for polyester - Disclosed is a method for increasing the solid state polymerization (SSP) rates of organic titanate catalyzed polyester. The method comprises in a first step, reacting a dicarboxylic acid or a C | 01-01-2009 |
| 20090143561 | Process for producing polyester with metal phosphonic acid complex catalysts - Disclosed is a method for the preparation of a polyester, which method comprises in a first step, reacting a dicarboxylic acid or a C | 06-04-2009 |
| 20100233405 | Stabilized Blends of Polyester and Polyamide - Disclosed are stabilized blends of polyester and polyamide. The polymer blends are stabilized with A) a combination of stabilizers a) acetaldehyde scavengers and b) stabilizers selected from phenolic antioxidants, organic phosphorus stabilizers and lactone stabilizers or B) a combination of c) lactone stabilizers and d) stabilizers selected from phenolic antioxidants and organic phosphorus stabilizers. The present blends exhibit reduced color formation, a high level of whiteness/brightness and acceptably low haze formation upon heat treatment. The blends are useful to make bottles, containers and films for drinks, food and cosmetics and the like. The polyester is in particular polyethylene terephthalate, PET, and the polyamide is in particular polyamide-MXD6. Heat treatment is for example melt extrusion or solid state polymerization, SSP. | 09-16-2010 |
| 20100233406 | Stabilized Blends of Polyester and Polyamide - Disclosed are stabilized blends of polyester and polyamide. The polymer blends are stabilized with A) one or more lactone stabilizers, B) one or more di-hydrocarbyl hydrogen phosphonates or one or more di-hydrocarbyl hydrogen phosphonites or C) one or more monoacrylate esters of 2,2′-alkylidenebisphenol antioxidants. The present blends exhibit reduced color formation, a high level of whiteness/brightness and acceptably low haze formation upon heat treatment. The blends are useful to make bottles, containers and films for drinks, food and cosmetics and the like. The polyester is in particular polyethylene terephthalate, PET, and the polyamide is in particular polyamide-MXD6. Heat treatment is for example melt extrusion or solid state polymerization, SSP. | 09-16-2010 |
