  invention provides a process for the production of polyetherester polyols which have hydroxyester groups terminally bound via ester groups to high molecular weight polyether polyol segments. These are produced by first reacting high molecular weight polyoxyalkylene ether polyols with molecular weights of from about 400 to 10,000 with an excess of dicarboxylic acids, dicarboxylic acid anhydrides or dicarboxylic acid esters, and then reacting the intermediate product in a further stage with an excess of diols, based on carboxyl groups. The new, high molecular weight polyetherester polyols thus consist of polyoxyalkylene ether segments, which have terminal ester segments in each case with terminal hydroxyl groups per end group. Moreover, the use is claimed of the high molecular weight polyetherester polyols as polyhydroxyl compounds for forming polyurethanes.

  本发明提供了一种聚醚酯多元醇的生产工艺，这种多元醇具有通过酯基与高分子量聚醚多元醇段末端结合的羟酯基团。生产方法是：首先将分子量在 400 至 10 000 之间的高分子量聚氧亚烷基醚多元醇与过量的二羧酸、二羧酸酐或二羧酸酯反应，然后再将中间产物与过量的以羧基为基础的二元醇反应。 这样，新的高分子量聚醚酯多元醇就由聚氧亚烷基醚段组成，在每种情况下，聚氧亚烷基醚段都具有末端酯段，每个末端基团都具有末端羟基。 此外，高分子量聚醚酯多元醇还可用作形成聚氨酯的多羟基化合物。
