摘要
The polyester polyols according to the invention with an average equivalent weight in the range from 200 to 4,000, which were prepared by reacting &agr;,&ohgr;-dicarboxylic acids with butane 1,4-diol, hexane 1,6-diol, propane 1,3-diol or pentane 1,5-diol and with polyols having 3 to 6 hydroxyl groups, are used for the preparation of PUR pourable elastomers with improved resistance to hydrolysis.
