- 3. A process as defined in claim 1, wherein ethylene oxide, propylene oxide, diglycidyl-ether or styrene oxide is used as the component (b).
- 4. A process as defined in claim 3, wherein ethylene oxide is used as the component (b).
- 5. A process as defined in claim 1, wherein at least one metal alcoholate of the formula
- Me(OX').sub.n
- wherein Me and n have the meaning indicated in claim 1 and X' denotes alkyl with 1 to 4 carbon atoms, phenyl, benzyl or cycloalkyl with at most 12 ring carbon atoms, is used as the component (c).
- 6. A process as defined in claim 1, wherein at least one metal alcoholate of the formula

- wherein Me.sub.1 denotes niobium.sup.V, tantalum.sup.V, tungsten.sup.VI, molybdenum.sup.VI, zirconium.sup.IV or hafnium.sup.IV and n denotes 4, 5 or 6, corresponding to the valency of the metal, and X has the meaning indicated in claim 1, is used as the component (c).
- 7. A process as defined in claim 6, wherein at least one metal alcoholate of the formula
- Me.sub.2 (O--X).sub.n.sbsb.1 '
- wherein Me.sub.2 denotes zirconium.sup.IV, niobium.sup.V, tantalum.sup.V or tungsten.sup.VI and n.sub.1 denotes 4, 5 or 6, and X represents alkyl with 1 to 4 carbon atoms, is used.
- 8. A process as defined in claim 1, wherein sodium hydroxide or potassium hydroxide or a sodium alcoholate or a potassium alcoholate of an alkanol with 1 to 4 carbon atoms, is used as component (d).
- 9. A process as defined in claim 1, wherein the reaction is carried out at 30.degree. to 120.degree. C.
- 10. A process as defined in claim 9, wherein the reaction is carried out at 40.degree. to 90.degree. C.
- 11. A process as defined in claim 1, wherein the reaction is carried out at a pressure of 1 to 11 atmospheres gauge.
- 12. A process as defined in claim 1, wherein 0.05 to 5%, preferably 0.1 to 2%, relative to the weight of the reaction mixture, of the components (c) and (d) together are employed.
- 13. A process as defined in claim 12, wherein the components (c) and (d) are employed in a weight ratio to one another of 9:1 to 1:9, preferably 4:1 to 1:4.
