摘　　要：硫酸与聚乙烯醇(PVA)经酯化制备PVA聚阴离子电解质.分别考察了反应时间、反应温度等对取代度的影响.采用红外光谱(IR)、扫描电镜(SEM)对硫酸酯化PVA聚阴离子电解质的结构进行了表征,测定了其热稳定性和导电性.Poly（vinyl alcohol） （PVA） - based polyanion was prepared by esterification of PVA with sulfuric acid. The influences of reaction temperature and time, the amount of sulfuric acid and water on the degree of substitution were investigated. The chemical structure and morphology of the polyanion characterized by FTIR and SEM respectively. The thermostability and conductibility of the polyelectrolyte were measured.
