摘要
The polyether polyol is prepared by a process comprising the continuous addition of the starting material and the alkylene oxide. The feed of the starting is stopped when 80 to 95% of the alkylene oxide has been fed to the reactor. This method produces a product with a narrow molecular weight distribution.
