Double metal cyanide catalysts for the production of polyetherpolyols

摘要

Double metal cyanide (DMC) catalyst contains: (a) double metal cyanide compound(s); (b) organic complex ligand(s), other than (c), and (c) ionic surfactant(s). Independent claims are also included for: (1) A process for producing polyether polyols by polyaddition of alkylene oxides to starter compounds containing active hydrogen atoms in the presence of the catalyst(s). (2) Polyether polyols produced by this process. (3) The production of the catalyst.
