Method for producing highly-branched glycidol-based polyols |
摘要 |
This invention relates to as process for the preparation of highly-branched polyols by polymerization of glycidol in the presence of a hydrogen-active starter compound with basic catalysis, wherein glycidol is added in dilute solution and the solvent used for the dilution is continuously distilled off. The polyols thus prepared are colorless, contain as the core unit solely the starter compound used and have polydispersities of less than 1.7.
