摘　　要：采用60Co-γ射线辐射引发溶液聚合制备了聚丙烯酸-丙烯酰胺吸水树脂,研究了吸水树脂中丙烯酰胺用量、辐射剂量、颗粒大小、表面处理对树脂吸液速率的影响。结果表明:当丙烯酰胺用量为12.5%(m/m)、辐射剂量为3.5 KGy、颗粒大小为31.8～127 mm、表面处理剂用量为0.5%(m/m)时,可制备吸蒸馏水速率为140 s,吸0.9%(m/m)的氯化钠溶液速率为80 s的吸水树脂。^60Co gamma rays was used to initiate solution polymerization to produce poly （acrylic acid-acrylamide）-absorbent resin. The influences of acrylamide dosage, radiation dose, particle size and surface treatment on absorbency ratio of resin were investigated. The results showed that the rate of absorbing distilled water and 0.9%（ mass fraction ）sodium chloride solution was 140 s, 80 s, respectively, when the amount of acrylamide was 12.5%（ mass fraction）, dose of radiation was 3.5 KGy, particle size was 31.8-127 mm and dose of surface treating agent was 0.5%（ mass fraction）.
