A polyester polyol made from natural oil feedstocks is disclosed. Methods for making the polyol are also disclosed. The method comprises reacting hydroxylated fatty acid/alkyl esters with a multifunctional ester-reactive initiator compound to form the polyester polyol. In one embodiment, the hydroxylated fatty acid/alkyl esters are made by hydroxylating fatty acid/alkyl esters having up to ninety-five percent by weight monounsaturation.
本发明公开了一种由天然油类原料制成的聚酯多元醇。还公开了制备聚酯多元醇的方法。该方法包括将羟基化
脂肪酸/烷基酯与多功能酯反应的
引发剂化合物反应以形成聚酯多元醇。在一种实施例中,羟基化
脂肪酸/烷基酯是通过对具有高达95%单不饱和度的
脂肪酸/烷基酯进行羟基化制备的。
