摘　　要：采用自由基氧化还原引发体系引发醋酸乙烯酯在室温下聚合制备聚醋酸乙烯酯乳液(俗称白乳胶),并与传统的热引发体系进行了比较。考察了氧化还原剂及交联剂N羟甲基丙烯酰胺用量对聚合物乳液性能的影响,得到了耐水性、耐寒性等粘接性能和使用性能优异而生产成本低的白乳胶。Poly(vinyl acetate) (white emulsion) was prepared by radical oxidation-reduction system at room temperature. The property of the product was compared to the other products prepared by using heat decomposing initiator.Meanwhile the effects of N-HMAN and oxidation-reduction initiator contents on white emulsion properties were discussed. The research results showed that the polyvinyl acetate white emulsion could be prepared at low cost and has excellent properties.
