METHOD FOR PREPARING METAL CYANIDE CATALYSTS USING POLYMERIZABLE COMPLEXING AGENTS

Complexes of a metal cyanide polymerization catalyst and certain monomer complexing agents provide a method whereby heterogeneous, active metal cyanide catalysts can be prepared. The catalysts are useful alkylene oxide polymerization catalysts that are easily separated from the polymerization produc...

Zusammenfassung:Complexes of a metal cyanide polymerization catalyst and certain monomer complexing agents provide a method whereby heterogeneous, active metal cyanide catalysts can be prepared. The catalysts are useful alkylene oxide polymerization catalysts that are easily separated from the polymerization product and recycled.
