Method of making a polyether using a double metal cyanide complex compound

Claim 1

THE METHOD FOR MAKING A POLYETHER WHICH COMPRISES MIXING AT LEAST ONE POLYMERIZABLE ORGANIC CYCLIC OXIDE MONOMER HAVING A RING OF FROM 2 TO 3 CARBON ATOMS AND ONE OXYGEN ATOM WITH A PARTICULATE CATALYST AND POLYMERIZING SAID MONOMER THROUGH ITS CYCLIC OXIDE GROUP TO FORM A POLYETHER IN ADMIXTURE WITH SAID CATALYST, SAID CATALYST BEING USED IN A MINOR AMOUNT BY WEIGHT SUFFICIENT TO POLYMERIZE SAID MONOMER TO FORM SAID POLYMER AND COMPRISING A DOUBLE METAL CYANIDE COMPLEX COMPOUND WHEREIN ONE OF THE METALLS OF SAID COMPLEX COMPOUND IS SELECTED FROM THE GROUP CONSISTING OF ZN(II), FE(II), FE(III), CO(II), NI(II), MO(IV), MO(VI), AL(III), V(IV), V(V), SR(II), W(VI), W(IV), MN(II), AND CR(III) AND MIXTURES THEREOF, WHEREIN THE OTHER METAL OF SAID COMPLEX COMPOUND IS A MEAL SELECTED FROM THE GROUP CONSISTING OF FE(II), FE(III), CO(II),, CO(III), CR(III), CR(II), MN(II), MN(III), V(IV), AND V(V), AND MIXTURES THEREOF, AND WHEREIN SAID DOUBLE METAL CYANIDE COMPLEX COMPOUND HAS BEEN TREATED WITH AT LEAST ONE ORGANIC MATERIAL SELECTED FROM THE GROUP CONSISTING OF AN ESTER OF A CARBOXYLIC ACID, A CYCLIC ETHER AND AN ACYCLIC ALIPHATIC SATURATED MONOETHER TO IMPROVE THE ACTIVITY OF SAID COMPLEX COMPOUND FOR THE POLYMERIZATION OF SAID MONOMER, SAID ORGANIC MATERIAL BEING INERT TO POLYMERIZATION BY SAID COMPOUND.

Claim 2

THE METHOD FOR MAKING A POLYETHER WHICH COMPRISES MIXING AT LEAST ONE POLYMERIZABLE ORGANIC CYCLIC OXIDE MONOMER HAVING A RING OF FROM 2 TO 3 CARBON ATOMS AND ONE OXYGEN ATOM WITH A PARTICULATE CATALYST AND POLYMERIZING SAID MONOMER THROUGH ITS CYCLIC OXIDE GROUP TO FORM A POLYETHER IN ADMIXTURE WITH SAID CATALYST, SAID CATALYST BEING USED IN A MINOR AMOUNT BY WEIGHT SUFFICIENT TO POLYMERIZE SAID MONOMER TO FORM SAID POLYMER AND COMPRISING A DOUBLE METAL CYANIDE COMPLEX COMPOUND WHEREIN ONE OF THE METALLS OF SAID COMPLEX COMPOUND IS SELECTED FROM THE GROUP CONSISTING OF ZN(II), FE(II), FE(III), CO(II), NI(II), MO(IV), MO(VI), AL(III), V(IV), V(V), SR(II), W(VI), W(IV), MN(II), AND CR(III) AND MIXTURES THEREOF, WHEREIN THE OTHER METAL OF SAID COMPLEX COMPOUND IS A MEAL SELECTED FROM THE GROUP CONSISTING OF FE(II), FE(III), CO(II),, CO(III), CR(III), CR(II), MN(II), MN(III), V(IV), AND V(V), AND MIXTURES THEREOF, AND WHEREIN SAID DOUBLE METAL CYANIDE COMPLEX COMPOUND HAS BEEN TREATED WITH AT LEAST ONE ORGANIC MATERIAL SELECTED FROM THE GROUP CONSISTING OF AN ESTER OF A CARBOXYLIC ACID, A CYCLIC ETHER AND AN ACYCLIC ALIPHATIC SATURATED MONOETHER TO IMPROVE THE ACTIVITY OF SAID COMPLEX COMPOUND FOR THE POLYMERIZATION OF SAID MONOMER, SAID ORGANIC MATERIAL BEING INERT TO POLYMERIZATION BY SAID COMPOUND.
