PROCESS FOR ENHANCING THE MOLECULAR WEIGHT OF A POLYESTER |
| 摘要 |
The molecular weight of a semi-crystalline starting polyester comprising ethylene 2,5- furandicarboxylate units is enhanced by heating the semi-crystalline starting polyester, having a melting point Tm, at a temperature in the range of (Tm-40°C) to Tm to obtain a solid stated polyester, wherein the semi-crystalline starting polyester has an intrinsic viscosity of at least 0.45 dL/g, and an amount of carboxylic acid end groups in the range of 15 to 122 meq/kg. |
