摘　　要：介绍了Irganox HP-136在PP加工中的作用，表明它能有效地捕获烷基自由基．与传统的受阻酚类及亚磷酸酯类抗氧剂复配与传统的二元抗氧稳定体系相比，具有添加量少、抗氧性能优等优点。比较了Irganox HP-136（3-芳基-苯并呋喃酮）与传统抗氧剂的抗氧机理．并分析了在聚合物稳定体系中的作用。Irganox hydrocarbon HP-136 （3-arylbenzofuranones）have been found to be fast acting radical scavengers, which can efficiently trap radicals. It can act as a important role for stabilization for PP in the processing. Irganox HP-136 and the oxidation resistant mechanism of the traditional antioxidants were compared, and the role of Irganox HP-136 in the stabilization for PP were discussed.
