실험 절차

166 g of a starting substance, diglycerin, 32 g of a catalyst, potassium hydroxide, 9,290 g of propylene oxide, and 1,460 g of butylene oxide were put into a 15-L autoclave, and reacted at 110° C. for 16 hours, and then neutralized, desalted and purified to obtain 9,900 g of a tetra-functional propylene oxide-butylene oxide copolymer. This polymer had a molecular weight of 10,900 (as calculated from its hydroxyl value).

후처리
