In this study, xanthan gum (XG) based hydrogels were prepared at a paste like state, in the presence of acetylene gas and CCl₄ through γ-irradiation. Sodium polyacrylate/XG semi-interpenetrating networks [P(AAcNa)/XG semi-IPNs] were also prepared and characterized. It was determined that XG could not undergo high gelation when irradiated at a paste like state. Relatively higher gelation was obtained in the presence of CCl₄. Irradiations carried out in the presence of acetylene resulted in formation of insoluble structures and viscosity of XG increased almost threefold up to a certain dose. Hydrogel structures with superabsorbent character and highest gelation were obtained with P(AAcNa)/XGsemi-IPNs. Swelling and absorbency under load (AUL)tests showed that P(AAcNa)/XG semi-IPNs have as much fluid absorption capacity as commercially available super absorbent polymers (SAPs). Basic network structural parameters of the P(AAcNa)/XG semi-IPNs were also calculated and characterized by mechanical and rheological tests. It was determined that the addition of XG to the P(AAcNa) structure greatly enhanced the mechanical strength of the hydrogels while fluid absorption capacities were adequately high for a novel XG based superabsorbent hydrogel.

在这项研究中，在乙炔气体和 CCl ₄的存在下，通过 γ 辐射制备了糊状状态的黄原胶 (XG) 基水凝胶。还制备并表征了聚丙烯酸钠/XG 半互穿网络 [P(AAcNa)/XG semi-IPNs]。确定XG在糊状状态下照射时不能发生高度凝胶化。在 CCl ₄存在下获得了相对较高的凝胶化. 在乙炔存在下进行的辐照导致形成不溶性结构并且 XG 的粘度在达到一定剂量时几乎增加了三倍。使用 P(AAcNa)/XGsemi-IPNs 获得了具有超吸收特性和最高凝胶化的水凝胶结构。负载下的溶胀和吸收性 (AUL) 测试表明，P(AAcNa)/XG 半 IPN 具有与市售高吸水性聚合物 (SAP) 一样多的液体吸收能力。还计算了 P(AAcNa)/XG 半 IPNs 的基本网络结构参数，并通过机械和流变测试对其进行了表征。结果表明，将 XG 添加到 P(AAcNa) 结构中大大提高了水凝胶的机械强度，同时对于新型 XG 基超吸收水凝胶而言，流体吸收能力足够高。
