PROCESS FOR PREPARING POLYETHER POLYOL USING DMC CATALYST AND CONTINUOUS ADDITION OF STARTER
Polyether polyols are made by a process that includes a continuous addition of starter and alkylene oxide. The feed of starter is discontinued when 80 to 95% of the alkylene oxide has been fed to the reactor. This process produces a product with a narrow molecular weight distribution.
