Patent

CA 2343319

The invention relates to novel double metal cyanide (DMC) catalyst for the preparation of polyether polyols by polyaddition of alkylene oxides to starter compounds containing active hydrogen atoms, wherein the catalyst contains a) double metal cyanide compounds, b) organic complex ligands other than c), and c) polyalkylene glycol sorbitan esters. The catalysts according to the invention have greatly increased activity in the preparation of polyether polyols.

L'invention concerne de nouveaux catalyseurs à base de cyanure bimétallique pour la préparation de polyols de polyéther par polyaddition d'oxydes d'alkylène sur des composés initiateurs présentant des atomes d'hydrogène actifs, lesdits catalyseurs contenant a) des composés de cyanure bimétallique; b) des ligands de complexe organiques différents de c); et c) des esters de polyalkylèneglycol de sorbitane. Ces catalyseurs présentent, lors de la préparation de polyols de polyéther, une activité fortement augmentée.
