摘　　要：分别研究了弹性体、成核剂DICPK、BaSO4 、光稳定剂UV 531、UV 770及其复合体系对耐候聚丙烯老化性能的影响。结果发现 ,所研制的耐候聚丙烯老化后的拉伸强度保持率、伸长率保持率。Effects of elastomer, nucleating agent, inorganic rigid particles and light stabilizers which involved UV 531 and UV 770 on the weathering resistance of PP were studied. The results showed that the retained tensile strength, elongation at break and impact strength were superior to the critarion of weatherproof PP.
