摘　　要：以2-丙烯酰胺基-2-甲基丙磺酸(AMPS)、丙烯酸(AA)、丙烯酰胺(AM)、壳聚糖(CTS)为单体,以N,N,-亚甲基双丙烯酰胺(NMBA)为交联剂,在不加入引发剂和不通入氮气保护的情况下,采用紫外固化法合成出AMPS/AA/AM/CTS四元共聚高吸水性树脂。用正交实验法获得最佳单体配比,并考察了其它因素对树脂吸水率的影响,借助FTIR、TG、偏光显微镜和原子力显微镜对树脂的结构、热稳定性和表面形态进行了分析。实验结果表明:优化条件下得到的高吸水树脂其吸蒸馏水倍数为780g/g,吸0.1mol/LNaCl倍率为55g/g。Using N, N＇-methylene bisacrylmide（NMBA）as cross linking agent, a superabsorbent of acrylic acid （AA）, 2-acrylamido-2-methylpropanesulfonic aeid（AMPS）, acrylamide（AM）, CTS as the monomer, quaternary eopolymer superabsorbent, which was prepared via ultraviolet irradiation without initiator and nitrogen atmosphere was prepared. The best reaction condition was based on the orthogonal experiment design, the influences of reaction conditions on water ab- sorbency were investigated by single factor experiment. The molecular structure and surface morphology were characterized by FT-IR, TG, microscopy and AFM. The results showed that the absorbency of copolymer was 780 （g/g）for distilled water and 55（g/g）for salt equation（0, lmol/L）in optimized conditions.
