摘要
本文研究在水介质中,α-甲基丙烯酸在高压聚乙烯颗粒表面进行的非均相接枝共聚反应,它的接枝度随反应时间.反应温度、单体浓度及引发剂浓度的增加而提高.并用扫描电镜、红外光谱,差热分析及裂解色谱等方法,分析证实了接枝链结构的存在。
The heterogeneous graft copolymerization of a-methylacrylic acid on the surface of H-press.polyethylene granules was investigated in a medium of water. The grafting degree increases with the concentration of monmer,initiator, reaction time and temperature.The presence of grafted polymethylic acrylic acid chain structure was verified and analysed by SEM,DTA,infrared absorption spectroscopy,pyrolysis gas chromatography,etc.
