摘要： 采用本体聚合的方法,在氧化苯甲酰(BPO)存在下,合成了顺丁烯二酸二丁基锡-苯乙烯-丙烯酸丁酯(DBTM-St-BA)三元共聚物.用GPC,FTIR,1H NMR,TG和刚果红法及布拉本热流变仪对共聚产物的结构和性能进行了表征.结果表明,在所选定的聚合条件下,共聚产物为DBTM-St-BA的三元共聚物,在含锡量相同的情况下,共聚物对PVC的热稳定效果和加工性能的影响优于DBTM,可以作为多功能化的PVC热稳定剂

关键词: 三元共聚物, 结构, 性能, 表征, PVC热稳定剂

Abstract: Benzoic peroxide(BPO) was used as an initiator in bulk terpolymerization of dibutyltin maleate, styrene and butyl acrylate(DBTM-St-BA). The structure and properties of the copolymer were characterized by GPC, IR, 1H NMR, TGanalysis, Congo red test and dynamic thermoreheological test. The results showed the occurrence of copolymerization. The number-average molecular weight of terpolymer was above 104. The thermal stability and flowability in PVCprocess of copolymer was superior to that of DBTM. It may be used as polyfunctional PVC stabilizer.

Key words: Terpolymer, Structure, Property, Characterization, PVC stabilizer
