SUSPENSIONS OF PLATELIKE MULTIMETAL CYANIDE COMPOUNDS, THEIR PRODUCTION AND THE USE THEREOF FOR PRODUCING POLYETHER ALCOHOLS

摘要

Catalyst suspensions for the ring-opening polymerization of alkylene oxides comprisea) at least one multimetal cyanide compound having a crystalline structure and a content of platelet-shaped particles of at least 30% by weight, based on the multimetal cyanide compound, andb) at least one organic complexing agentc) water and/ord) at least one polyether and/ore) at least one surface-active substance, with the proviso that at least component a) and at least two of the components b) to e) have to be present.
