摘要
本文介绍了为提高聚醋酸乙烯乳液稳定性、耐水性和防冻性而进行缩醛化改性的原理，并确定了最佳工艺条件即甲醛与聚乙烯醇的配比为０．４５～０．５０。
Polyvinyl acetate emulsion can be improved in its stability and ability to resistwater and prevent frost after the process ofacetalation. This article introduces the principle of acetalation and the selection of theoptimal technological condition,and it defines the ingredient proportion of methanalto PVA to be 0. 45～0. 50.
