POLYESTER POLYOLS FROM RECYCLED POLYMERS AND WASTE STREAMS |
| 摘要 |
The present invention relates to polyester polyols made from aromatic polyacid sources such as thermoplastic polyesters. The polyols can be made by heating a thermoplastic polyester such as virgin polyethylene terephthalate, recycled polyethylene terephthalate, or mixtures thereof, with a glycol to give a digested intermediate which is then reacted with a digestible polymer, which can be obtained from various recycle waste streams. The polyester polyols comprise a glycol-digested polyacid source and a further digestible polymer. The polyester polyols provide a sustainable alternative to petrochemical or biochemical based polyester polyols. |

1. A polyester polyol made by a process comprising:
(a) heating an aromatic polyacid source with a glycol to give a digested intermediate; and (b) reacting the resulting digested intermediate with a digestible polymer containing a functional group selected from an ester, amide, ether, carbonate, urea, carbamate, glycoside, and isocyanurate, or combinations thereof;wherein the molar ratio of glycol to aromatic polyacid source is at least 0.8, and the polyol has a hydroxyl number within the range of about 10 to about 800 mg KOH/g. |
