Patent

CA 2355727

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.

L'invention concerne un procédé qui permet de produire des polyols hautement ramifiés en polymérisant le glycidol, en présence d'un composé de départ à activité hydrogène, par catalyse basique. Le procédé consiste à ajouter audit composé de départ du glycidol en solution diluée et à distiller en continu le diluant utilisé pour la dilution. Le polyols ainsi produits sont incolores, contiennent comme seules unités de base les composés de départ utilisés et possèdent une polydispersité inférieure à 1,7.
