【摘要】 本研究对p-乙烯基苯磺酸正丁酯(BPSS)与甲基丙烯酸甲酯(MMA)按不同比例共聚得到的二元共聚物进行了较系统的热性能研究。通过DSC和IR分析测试手段,发现该类聚合物在200-240℃发生热分解,聚合物中的磺酸酯基团能够在较短时间内分解生成磺酸,并且其热分解表现出自加速效应。同时,进一步研究表明在加入三苯胺硫盐热生酸剂后,磺酸酯基团热分解所需能量大幅度降低,并且实现中性水溶所需烤版时间也有所减少,聚合物能够发生较大的亲和性变化。更多还原

【Abstract】 In this study,thermolysis properties of a series of bipolymers with n-butyl p-styrenesulfonate(BPSS)and methyl methacrylate(MMA) in different ratio were investigated.By using DSC and IR,it was indicated that these bipolymers were thermo-decomposed at 200-240℃ and sulfonate unit could produce sulfonic acid in a relatively short time and its thermo-decomposition showed a self-acceleration effect.And further experiment results indicated that the thermo-decomposition energy of sulfonate unit largely reduced and the baking time of a polymer dissolving in neutral water also decreased when thermal acid generator was added,showing the polymers had a great affinity switch.更多还原
