DOPPELMETALLCYANID-KATALYSATOREN FÜR DIE HERSTELLUNG VON POLYETHERPOLYOLEN |
摘要 |
This invention relates to novel double metal cyanide (DMC) catalysts for the production of polyether polyols by polyaddition of alkylene oxides onto starter compounds having active hydrogen atoms, wherein the catalyst contains a) double metal cyanide compounds, b) organic complex ligands other than c) and c) ionic surface- or interface-active compounds. The catalysts according to the invention have greatly increased activity in the production of polyether polyols. |
