采用预辐照法在聚3-羟基丁酸酯膜上接枝乙酸乙烯酯。接枝反应分别在醋酸乙烯酯/水/表面活性剂乳液、醋酸乙烯酯/水和醋酸乙烯酯/甲醇体系中进行。对于乳液接枝，就单一乳液层的稳定性而言，确定了Nonion L-4是最佳的表面活性剂。具有10：1（w/w）的VAc与表面活性剂的比率的乳液产生最高的接枝度：23%。评价了在乳液、水和甲醇溶剂中的接枝效率。结果表明，当VAc质量分数为2%时，乳液的接枝效率是VAc/甲醇乳液的100倍。© 2007 Wiley Periodicals，Inc.应用聚合物科学杂志，2008年
Vinyl acetate (VAc) was grafted onto poly(3-hydroxybutyrate) film by a preirradiation method. Grafting reactions were carried out in VAc/water/surfactant emulsion, VAc/water, and VAc/methanol systems. For emulsion grafting, Nonion L-4 was ascertained to be the optimum surfactant with respect to the stability of a single emulsion layer. The emulsion with a 10 : 1 (w/w) ratio of VAc to surfactant yielded the highest degree of grafting: 23%. The grafting efficiency in the emulsion and the water and methanol solvents were evaluated. The results indicated that the grafting efficiency of the emulsion was 100 times that of VAc/methanol when the same 2 wt % VAc was used in the grafting reaction. © 2007 Wiley Periodicals, Inc.
