摘　　要：由丙烯酸钠 (AANa)与氯化聚乙烯 (CPE)制备吸水膨胀性橡塑材料 (WSM)。在混炼过程中 ,由于力化学原因 ,CPE产生断链并形成链自由基 ,后者与丙烯酸钠反应形成 CPE的丙烯酸钠接枝聚合物 ,经硫化交联制得吸水膨胀性橡塑材料在水中稳定性好 ,未发现亲水组分析出。但 AANa和 CPE的物理混合物一经浸水 ,亲水性的 AANa将全部析出。混合物的浸水质量损失率为 10 0 %。The water swelling rubber like plastic material(WSM) was prepared by blending chlorinated polyethylene(CPE) with sodium acrylate(AANa). The shear force occurred in the process of mixing caused the formation of CPE chain free radicals which reacted with sodium acrylate to give graft polymer. WSM obtained was stable in water with a little loss of hydrophilic polymer moiety even for 30 days. But the simple physical mixture of AANa and CPE lost almost all of its mass after immersion in water for the same time.
