摘　　要：本文系统地研究了地超声波辐照下聚氧化乙烯(PEO)在其水溶液中与甲基丙烯酸己酯(HMA)的非均相共聚反应。结果表明,PEO超声降解产生的自由基可引发HMA聚合,形成PEO-HMA共聚物,该共聚物在超声波辐照下可进一步降解。通过红外光谱、裂解气相色谱及核磁共振分析表明,所得共聚物为嵌段共聚物。The ultrasonic heterogeneous copolymerization of poly (ethylene oxide) (PEO) in its aqueous solution with hexyl methacrylate (HMA) was studied. The experimental results show that the macroradicals praduced in the ultrasenic degradation of PEO can initiate the polymerization of HMA. The copolymer (PEO-HMA) thus formed will be degraded further as the irradiation goes through. The structure of the copolymer was idontified by IR, PGC and NMR, it is a block one.
