摘要

采用沉淀法合成了硅酸镁。用无机离子交换剂镁硅酸盐浸渍聚丙烯酰胺丙烯酸和聚丙烯酰胺丙烯腈,在辐射剂量为25、65和90 KGy的条件下进行聚合反应,合成了聚丙烯酰胺丙烯酸和聚丙烯酰胺丙烯腈。采用序贯x射线荧光光谱仪、x射线衍射仪、差热-热重分析和红外光谱分析研究了复合材料的结构特征。研究了复合材料的形成机理,结果表明,复合材料的聚合过程是在烃链上通过加成聚合进行的,而硅酸镁的浸渍是通过缩聚聚合进行的。

Polymeric Composite Materials Based on Silicate: I-Synthesis, Characterization and Formation Mechanism
Magneso-silicate has been synthesized by precipitation technique. Polyacrylamide acrylic acid and polyacrylamide acrylonitrile impregnated with inorganic ion exchanger, magneso-silicate, have been synthesized by subjected co-monomers to gamma radiation initiated polymerization at radiation doses 25, 65 and 90 KGy. The structure features of composites were investigated by sequential x-ray fluorescence spectrometer, x-ray diffraction, differential thermal- thermogravimetric analyses and infrared spectroscopy. Formation mechanism for these composites was conducted and the results obtained showed that the polymerization process was carried out in the hydrocarbon chain by addition polymerization whereas impregnation of magneso-silicate into the polymeric composites was carried out by condensation polymerization.
