摘　　要：研究了对苯二酚(HQ)、2,2,6,6-四甲基-4-羟基哌啶-1-氧自由基(SPJ-701)与对苯二酚(HQ)复配阻聚剂分别对AIBN(偶氮二异丁腈)引发的丙烯酸丁酯(BA)自由基聚合的阻聚效率。实验结果表明,复合阻聚剂SPJ701-HQ阻聚效果较好,聚合反应的诱导期长,说明氮氧自由基与HQ有协同效应。Inhibition effects of hydroquinone （HQ）, Complex Inhibitor of J-701 and hydroquinone （ HQ ）to BA free radicals polymerization faction initiated by azobisisobutyronitrile （AIBN）were studied. The result shows that the complex inhibitor of SPJ701 and HQ which has long polymerization reaction induction period, is better than HQ on inhibition efficiency. Therefore it is indicated that nitroxide radicals and HQ produces cooperative effect.
