PROCESS FOR PREPARING HIGH MOLECULAR WEIGHT POLYETHER POLYOLS
摘要:
The invention relates to a process for the preparation of polyether polyols with equivalent molecular weights of from 8,000 to 20,000 g/mol from one or more H-functional starter compounds and one or more alkylene oxides in the presence of a double metal cyanide catalyst, characterized in that the alkylene oxides are metered into the reactor in the course of from 15 to 23 h.
