摘　　要：以丁二酸为交联剂,对聚乙烯醇(PVA)胶进行改性;并对改性PVA胶的粘度、硬度、附着力、抗冲击力、固化程度和红外光谱进行测试。确定最佳改性条件如下:PVA胶质量浓度7%、反应温度85℃、PVA胶与丁二酸质量比5.6∶1,在此条件下,可得到性能优良的改性PVA胶。In this paper,the modification of polyvinyl alcohol（PVA） adhesive using succinic acid as cross-linking agent was studied,and the performance of modified PVA adhesive including viscosity,hardness,adhesion,shock resistance,curing degree and FTIR were investigated.The optimum modification conditions were obtained as follows：the mass concentration of PVA adhesive was 7%,the reaction temperature was 85 ℃,the mass ratio of PVA adhesive to succinic acid was 5.6∶1.Under above conditions,the modified PVA adhesive with excellent performance was obtained.
