| 摘 要： | 测定了几种浓度的聚乙烯醇（ＰＶＡ）水溶液辐照后的凝胶含量，随着吸收剂量的增大，凝胶含量增加，同一吸收测量下，随着ＰＶＡ浓度的增加，其凝胶含量先上升后趋于饱和，三聚氰酸，Ｎ，Ｎ′－亚甲基双丙烯酰胺和和六次甲基四胺等对ＰＶＡ水溶液的辐射交联有敏化作用，可使凝胶剂量降低。样品的电镜图也表明加入添加剂的ＰＶＡ水凝胶结构的差异。还测定了水凝胶的含水量与浸泡时间的关系及水凝胶的饱和含水量与吸收剂量的关系。

| Abstract: | The gel fractions of irradiated polyvinyl alcohol (PVA) aqueous solution have been measured. The gel fraction increases with absorbed dose. At same dose, the gel fraction increases with PVA concentration and gradually reaches a stabs turation state. Cyanuric acid, N,N'-methylene-bis-acrylamide and hexamethylene tetramine have sensitization effect for radiation crosslinking of PVA. The gelation dose decreased at that condition. The relationships between water content of PVA hydrogel with dose and swelling time have been measured. |
