Clear low viscosity high-functional polyethers based on saccharose

The invention relates to a process for the preparation of highly functional, low-viscosity, pale polyethers in which firstly, at temperatures of 20 - 110@C, an initiator mixture is prepared which contains: component A) 100 parts by weight of sucrose, component B) 30-1,000 parts by weight of a low-mo...

Zusammenfassung:	The invention relates to a process for the preparation of highly functional, low-viscosity, pale polyethers in which firstly, at temperatures of 20 - 110@C, an initiator mixture is prepared which contains: component A) 100 parts by weight of sucrose, component B) 30-1,000 parts by weight of a low-molecular-weight, polyhydric alcohol and/or an alkoxylation product thereof, component C) [0.5-3] . 10 parts by weight of an alkali metal hydroxide, and the mixture is subsequently reacted with alkylene oxides at 90 - 130@C and at pressures of 0.3 - 4 bar nitrogen overpressure.
