METHOD FOR PRODUCING POLYETHEROLS BY RING-OPENING POLYMERISATION OF ALKYLENE OXIDES |
摘要 |
A process for preparing polyetherols by ring-opening polymerization of alkylene oxides onto H-functional initiator molecules, which comprises at least one process step a) in which a compound of the formula (I) M'aM''b(OH)cOd*Ac*Lf (I), applied to a solid inert support or incorporated in the latter or molded to form a shaped body is used as catalyst, and at least one process step b) in which a multimetal cyanide compound of the formula (II) M1a[M2(CN)b(A)c]d.fM1gXn.h(H2O).eL (II) applied to a solid, inert support or incorporated in the latter or molded to form a shaped body or in powder or paste form is used as catalyst. |
