无机氧化物辐射接枝反应研究

以氧化铝、氧化镁为研究对象,在快电子束或γ射线作用下,进行甲基丙烯酸的辐射接枝。通过反应条件的研究,红外光谱、扫描电镜、X衍射等方法的表征,确认实现了无机物-有机单体的接枝聚合。着重用ESR方法研究了无机氧化物在电离辐射作用下的变化特点以及引发活性中心的性质,初步探讨了无机氧化物-有机单体的辐射接枝机制。

STUDY ON RADIATION GRAFTING REACTION OF INORGANIC OXIDES

In this paper, Al2O3, MgO as targets the radiation grafting of MAA by electron beams was studied. By the examination of the reaction conditions and materials characterizing by IR spectrum. Scanning electron microscopy,X-ray diffraction methods etc. ,it is reasonable concluded that grafting copolymerization of inorganic oxides and organic monomers has been confirmed. We focus our attention on using ESR spectrum to study the specialities in ionizing radiation of inorganic oxides and the properties of initiating active centers. In addition, the radiation grafting mechanism of inorganic oxides and organic monomers has been primarily investigated.
