摘　　要：采用聚偶氮酯引发剂,合成了聚苯乙烯/聚丙烯酰胺嵌段聚合物(PSt/PAM)。考察了含偶氮基聚苯乙烯预聚物(pre-PSt)在1,4-二氧六环中引发AM的聚合反应行为,讨论了影响第二单体转化率和聚苯乙烯均聚物含量的因素。用元素分析、溶解性、红外光谱、DSC、TG和裂解色谱表征了PSt/PAM嵌段聚合物。A polyazoester initiator was used to synthesize polystyrene/polyaerylamide (PSt/PAM) block polymers by its consecutive decomposition in styrene(St) and aerylamide(AM). The polymerization behavior of AM in 1,4-dioxane initiated by an azo group-containing styrene prepolymer (prePSt) was investigated, and the factors influencing the conversion of the second monomer and the content of the homopolystyrene were discussed. The PSt/PAM block polymers were characterized by elemental analysis, solubility, IR, DSC, TGand pyrolysis-gas chromatography.
