| Abstract: | Styrene-maleic anhydride copolymer was synthesized by solution sediment polymerization method with BPO as initiator and toluene as solvent.The effect of polymerization temperature,dosage of initiator,ratio of monomer and polymerization time on polymerization was researched in detail.The yield of the copolymer can reach 96.6% under the conditions of polymerization temperature 80 ℃,initiator dosage 0.7%,molar ratio of styrene to maleic anhydride 1∶1 and polymerization time 2 h.The structure of the copolymer was confirmed by 13C NMR,IR,GPC and elemental analysis.Also,the thermal stability of the copolymer was tested by TG.Based on the analytical results of HPLC of polymeric residual liquid,elemental analysis and 13C NMR of the copolymer,the structure of styrene-maleic anhydride copolymer is confirmed to be alternating copolymer. |
