Abstract The thermostability of polysterene with/without new styrylquinoline containing methacrylic fragments has been described in the present work. Polystyrene and copolymers based on styrene and new methacrylic styrylquinoline containing monomers were synthesized by free radical thermoinitiated polymerization in the presence of 2,2′-azobisisobutyronitrile (1 wt%) as initiator at inert atmosphere. The impact of 2-[2-(4-methoxyphenyl)ethenyl]quinolin-8-yl 2-methylpropyl-2-enoate (М1), 2-(2-phenylethenyl)quinolin-8-yl 2-methylpropyl-2-enoate (М2), 2-[2-(4-nitrophenyl)ethenyl]quinolin-8-yl 2-methylpropyl-2-enoate (М3) on thermal stability of polystyrene was investigated. The thermostability of polystyrene and copolymers ST:M1, ST:M2, ST:M3 were studied by dynamic thermograviametric analysis. It was shown that destruction of polystyrene with corresponding units M1-M2 starts at 41–42°С higher, than reference polystyrene.

含甲基丙烯酸酯的苯乙烯基喹啉稳定聚苯乙烯

摘要 目前的工作已经描述了含有/不含新的含有甲基丙烯酸片段的苯乙烯基喹啉的聚苯乙烯的热稳定性。在惰性气氛下，在 2,2'-偶氮二异丁腈（1 wt%）作为引发剂的存在下，通过自由基热引发聚合合成聚苯乙烯和基于苯乙烯和新的甲基丙烯酸苯乙烯基喹啉单体的共聚物。2-[2-(4-甲氧基苯基)乙烯基]喹啉-8-基2-甲基丙基-2-烯酸酯(М1)、2-(2-苯基乙烯基)喹啉-8-基2-甲基丙基-2-烯酸酯的影响(М2), 2-[2-(4-nitrophenyl)ethenyl]quinolin-8-yl 2-methylpropyl-2-enoate (М3) 对聚苯乙烯的热稳定性进行了研究。通过动态热重分析研究了聚苯乙烯和共聚物 ST:M1、ST:M2、ST:M3 的热稳定性。
