摘　　要：悬浮聚合合成醋酸乙烯酯-丙烯酸甲酯共聚物,在有机溶剂中碱性水解得吸水凝胶.研究了引发剂用量、MA比例和酸化度对悬浮聚合及凝胶的吸水性能的影响.发现这种无交联剂的水凝胶吸水率可达800mL/g.The P(VAcMA) was polymerized by suspension polymerization. The product was partially alkaline hydrolyzed in an organic solvent. The relationships between the water absorbing power of the polymer and the amount of initiator , ratio of the MA/VAc and acidified degree were studied. In case of deionizing water,the water absorbed by the polymer amount to 800 mL/g.
