| titleOfInvention |
Polyester polymers with low acetaldehyde generation and high vinyl end group concentration |
| abstract |
Polyester polymers comprising alkylene arylate units are prepared by adding a catalyst deactivator late in the polycondensation period or when/after remelting the solid polyester polymer, said polymer having an It.of at least 0.72 dl/g. V. A vinyl end group concentration of at least 0.8 microequivalents/gram and an AA formation rate of less than 20 ppm. |
