摘　　要：研究了羟乙基纤维素（ＨＥＣ）分别与甲基丙烯酸甲酯（ＭＭＡ）和丙烯酸（ＡＡ）在超声波辐照作用下的共聚反应；并研究了共聚物的纤维素酶降解；对降解产物进行了表征与分析。The copolymerization of hydroxyethyl cellulose (HEC) with methyl methacrylate (MMA) or acrylic acid (AA) was carried out by exposing the reactants solution to ultrasonic irradiation. The ezymatic degradation of the copolymers by using cellulose were studied. The chemical structure and molecular weight distributions of the remaining polymers were identified by IR, GPC and DSC analysis.
