摘要: 以过氧化苯甲酰(BPO)为引发剂,将顺丁烯二酸二丁基锡(DBTM)与苯乙烯(St)、甲基丙烯酸甲酯(MMA)进行本体三元共聚反应,探讨了共聚反应条件.用液相色谱、红外光谱、核磁共振氢谱和热重分析对共聚物的结构和性能进行了表征.动态热流变性实验结果表明,在含锡量相同的情况下,共聚物对PVC的热稳定效果优于DBTM,可以作为多功能化的PVC热稳定剂.

关键词: 三元共聚物, 合成, 表征, PVC热稳定剂

Abstract: Benzoic peroxide(BPO) was used as an initiator in bulk terpolymerization of dibutyltin maleate(DBTM), methyl methacrylate(MMA) and styrene(St). The conditions of copolymerization were discussed. The copolymer was characterized by GPC, IR, 1H NMRand TGanalysis; and the results showed the occurrence of copolymerization. The number-average molecular weight of terpolymer was above 104. The dynamic thermorheological test showed that, the thermal stability of copolymer was superior to that of DBTM. It may be used as polyfunctional PVCstabilizer.

Key words: Terpolymer, Synthesis, Characterization, PVC thermal stabilizer
