摘　　要：采用本体聚合法,制备了N-乙烯基吡咯烷酮(NVP)/甲基丙烯酸羟乙酯(HEMA)、NVP/HE-MA/EMA(甲基丙烯酸乙酯)和NVP/HEMA/BMA(甲基丙烯酸丁酯)3种不同的共聚水凝胶材料,并用重量法和TG法研究了这3种不同组成水凝胶的溶胀性能。研究结果表明:加入疏水性单体甲基丙烯酸酯类,共聚水凝胶溶胀性能下降,由于EMA与HEMA结构相似,相容性好,其对溶胀性能的影响比BMA的影响小。　Copolymers Hydrogel of NVP/HEMA,NVP/HEMA/EMA,NVP/HEMA/BMA was synthesized by means of bulk polymerization.And the properties of swelling behavior of the three different hydrogls was studied by the gravimetric and TG analysis.The results showed that methacrylate decreasing the water absorbency and water absorbent rate,but because of the similar structure of EMA and HEMA,the effect on the swelling behavior of EMA was less than that of BMA.
