Abstract
L'invention concerne un nouveau procédé pour la préparation de polyetherpolyols d'un poids moléculaire moyen de 200-10 000 et d'une fonctionnalité d'hydroxyle moyenne de 2,0-7,0. Le procédé selon l'invention se caractérise en ce que l'on fait réagir un ou plusieurs oxydes d'alkylène, le cas échéant successivement, avec un mélange de polyalcools préparé par autocondensation de l'hydrate d'aldéhyde suivie de réduction des produits de condensation, ledit mélange ayant été éventuellement additionné encore d'alcools difonctionnels et/ou trifonctionnels et/ou de mono- ou polyamines. Application : utilisation comme composants de réaction par atomes d'hydrogène réactifs vis-à-vis des isocyanates pour la préparation de matières plastiques de polyuréthannes.
