摘　　要：采用 (NH4) 2 S2 O8-NaHSO3 氧化还原引发剂和FeSO4催化剂 ,并辅之以助剂U和O ,于低温条件下(<6 5℃ ) ,通过正交试验 ,制得了转化率大于 95 %、固含量 2 3%左右、性能较佳的PVAc乳液。可直接用作木材、纸张、纸桶粘合剂、腻子胶和制作涂料。In low temperature condition(<65 ℃), using (NH 4) 2 S 2O 8-NaHSO 3 as redox agent, FeSO 4 as catalyst and promoter U and O polyv inyl acetate emulsion of good performance was prepared by the method of orthogo nal test. This emulsion which has high conversion (>95%) and low solid content ( about 23%) was directly used as adhesives for wood, paper, paper barrel, putty a nd coatings.
