摘　　要：利用发烟硝酸进行了聚硝基α-甲基苯乙烯的一步法合成,探讨了发烟硝酸用量、溶剂含量、聚合温度及反应时间对聚硝基α-甲基苯乙烯数均分子量及硝基导入率的影响。结果表明:低温极性溶剂有利于聚硝基α-甲基苯乙烯一步法合成的进行,发烟硝酸用量是影响硝基导入率的主要因素;以二氯甲烷为溶剂,在-65℃条件下反应30 min,聚硝基α-甲基苯乙烯的数均分子量及产率分别为14 683,70%。Polynitro α-methylstyrene was synthesized successfully by one-step method with fuming nitric acid. The impacts of content of fuming nitric acid, solvent, polymerization temperature and reaction time on number average molecular weight, nitro introduction of the polymer were studied. The experiment results show that low polymerization temperature, high polarity solvent are in favor of the reaction, the content of fuming nitric acid is the main factor that decides the import of nitro group. The molecular weight and the yield of the polymer are 14 683 and 70% respectively when running the reaction at-65 ℃ for 30 minutes with dichloromethane as the solvent.
