摘　　要：选用国产抗氧剂和光稳定剂,对小本体聚丙烯树脂进行了稳定化试验。通过加工稳定性,热老化和户外曝露等多项试验考核,证实所推荐的稳定化配方能够有效地抑制小本体聚丙烯树脂在加工过程中产生的热氧降解,也在不同程度上延长了它们的热氧化寿命和耐候寿命。Stabilization treatments of small bulk polypropylene (PP) resin were performed by using antioxidants and light stabilizers made in China. It was found in the tests for processing stability, oven ageing and outdoor ageing that the stabilization formulas proposed had proved effective on restraining the thermooxidizing degradation of small bulk PP resin during processing and also prolonged the thermooxidizing and weather resistance lives of the resin.
