process for the production of hochverzweigten polyols based on glycidol

摘要

The invention relates to a method for producing highly branched polyols by polymerising glycidol in the presence of a hydrogen-active starter compound with basic catalysis. Glycidol is added in a diluted solution and the solvent used for the dilution is continuously distilled off. The resulting polyols are colourless, contain the starter compound used only as a core unit and have polydispersities of less than 1.7.
