Versuchsvorschrift

In a 10 l autoclave, 92 g of glycerol, 24 g of potassium hydroxide, 6,970 g of propylene oxide and 1,100 g of butylene oxide were fed and reacted together at 110° C. for 15 hours. After the reaction has been completed, the mixture was neutralized and desalted to obtain 8,100 g of a trifunctional propylene oxide-butylene oxide random copolymer. Its molecular weight was 8,145 (calculated from its hydroxyl number).
