    Abstract: Polyester polyols made from thermoplastic polyesters are disclosed. The polyols are reaction products of a thermoplastic polyester, a glycol, and a hydrophobe selected from ricinoleic acid, ethoxylated castor oil, saturated or unsaturated C9-C18 dicarboxylic acids, tung oil, soybean oil, sunflower oil, cardanol-based products, recycled cooking oil, isostearyl alcohol, hydroxy-functional materials derived from epoxidized, ozonized, or hydroformylated fatty esters or fatty acids, and mixtures thereof. In one process, the polyols are made by reacting the thermoplastic polyester with a glycol to give a digested intermediate, which is then reacted with the hydrophobe. In another process, the thermoplastic polyester, glycol, and hydrophobe are combined and reacted in a single step. These hydrophobes facilitate the production from recycled thermoplastics of polyols that have good transparency and little or no particulate settling or phase separation. High-recycle-content polyols having desirable properties and attributes for formulating polyurethane products, including aqueous polyurethane dispersions, can be made. The polyols provide a sustainable alternative to bio- or petrochemical-based polyols.

    Abstract translation: 公开了由热塑性聚酯制成的聚酯多元醇。 多元醇是热塑性聚酯，二醇和选自蓖麻油酸，乙氧基化蓖麻油，饱和或不饱和C 9 -C 18二羧酸，桐油，大豆油，向日葵油，基于腰果酚的产品，再循环烹饪的疏水物的反应产物 油，异硬脂醇，衍生自环氧化，臭氧化或加氢甲酰化脂肪酸酯或脂肪酸的羟基官能材料及其混合物。 在一个方法中，多元醇通过使热塑性聚酯与二醇反应制得，得到消化的中间体，然后与疏水物反应。 在另一个方法中，将热塑性聚酯，二醇和疏水物在一个步骤中组合并反应。 这些疏水物促进了从具有良好透明性和很少或没有微粒沉降或相分离的多元醇的再循环热塑性塑料生产。 可以制备具有用于配制聚氨酯产品（包括水性聚氨酯分散体）的所需性质和特性的高回收含量的多元醇。 多元醇为生物或石油化学的多元醇提供了可持续的替代方案。
