実験手順
In a 15-liter autoclave were placed 166 g of diglycerol as a starting material, 32 g of potassium hydroxide as a catalyst, 9,290 g of propylene oxide, and 1,460 g of butylene oxide and the reaction was carried out for 16 hours at 110° C. Then, the reaction mixture was subjected to a neutralization treatment, a desalting treatment, and a purification treatment to obtain 9,900 g of a tetrafunctional propylene oxide-butylene oxide random copolymer. The molecular weight of the copolymer was 10,900 (as calculated by the hydroxyl group value).
