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.
