The study of hydrolysis of acetals indicated that the hydrolytic rate constant of acetals of O-9(was abbreviated for O-9s) was increased nearly 20 times after emulsified and those of theO-15s and O-20s were only improved 1.4 to 2.38 times.

• 研究了三种缩醛型聚醚的水解性能：O-9缩甲醛经乳化剂乳化后的水解速度比不乳化直接水解时快近20倍，而O-15缩甲醛和O-20缩甲醛经乳化剂乳化后水解速度只提高1.；4到2
