摘要研究了羟乙基纤维素（HEC）和聚氧化乙烯（PEO）在水溶液中的超声降解及HEC与PEO的共聚反应。用差热分析、红外光谱、质谱、X-射线衍射和偏光显微镜对共聚物的结构进行了表征。所得共聚物主要为嵌段共聚物。通过在25°C和18.2kHz下以2.5A输入电流在反向主电路上照射0.5%HEC/PEO水溶液10分钟的时间段，形成的共聚物的量为55.07%。
Abstract The ultrasonic degradation of hydroxyethylcellulose (HEC) and poly (ethylene oxide) (PEO) in aqueous solution, and the copolymerization of HEC with PEO were studied. The structure of the copolymer was identified by DTA, IR, MS, x-ray diffraction, and polarizing microscopy. The copolymer prepared is mainly block. The copolymer formed amounts to 55.07% by irradiating 0.5% HEC/PEO aqueous solution for a period of 10 min at 25°C and 18.2 kHz with 2.5 A input current on a reversed main circuit.
