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
