壳聚糖接枝甲基丙烯酸甲酯的动力学研究

Kinetic Study on Graft Copolymerization of MMA onto Chitosan

用动力学的方法研究了影响铈盐引发壳聚糖与甲基丙烯酸甲酯（ＭＭＡ）接枝共聚反应的一些因素．发现壳聚糖能与ＭＭＡ发生接枝反应，在稳态下，接枝速率与单体的量无关，与壳聚糖的浓度成正比．

Graft copolymerization of MMA onto chitosan in an acetic acid solutions was studied. The results show that at radical steady state, the rate of graft copolymerization is independent of MMA amount, and directly proportional to chitosan concentration.
