Highly active double metal cyanide catalysts |
摘要 |
A solid double metal cyanide (DMC) catalyst useful for epoxide polymerisation comprises: (a) a double metal cyanide cpd; (b) an organic complexing agent; and (c) about 5-80 wt% based on the amt of catalyst, of a polyether having a number average molecular wt greater than about 500. Also claimed are: Preparing a solid DMC catalyst in the presence of an organic complexing agent and a polyether as above, wherein the solid DMC catalyst contains 5-80 wt% of the polyether. Preparing a soli DMC catalyst useful for epoxide polymerisation. |
