Verfahren zur Herstellung von Polyetherpolyolen |
摘要 |
The invention relates to a method for preparing polyetherpolyols by means of a double metal cyanide (DMC)-catalysis, through which the induction phase is dramatically shortened. Through a continuously metered supply of an alkylene oxide to the starter-catalyst mixture, the induction phase can be dramatically shortened in comparison to a continuous activation. |
