聚苯乙烯辐射接枝丙烯酸的接枝共聚物,很难找到溶剂。因此用常规方法不易作它的结构分析。对于接枝位置,目前大多数学者认为,接枝反应发生在聚苯乙烯主链和苯环的对位上。本工作用固体核磁和红外光谱等手段进行研究,结果表明,以甲醇为溶剂,聚苯乙烯淹基体,采用予辐照方法,其接枝位置在聚苯乙烯的苯环间位上,这个辐照机理,对解释其聚合物
Polystyrene radiation grafted acrylic graft copolymer, it is difficult to find a solvent. Therefore, the conventional method is not easy to make its structural analysis. For the grafting position, at present most scholars believe that the grafting reaction occurs in the para-position of the polystyrene backbone and the benzene ring. The work of solid-state nuclear magnetic resonance and infrared spectroscopy and other means of study, the results show that the use of methanol as a solvent, polystyrene flooded matrix, the use of pre-irradiation method, the graft position in the benzene ring between the polystyrene, the spokes According to the mechanism, to explain its polymer
