摘　　要：通过聚丙烯(PP)树脂的加工稳定性试验和PP薄片的热烘箱老化试验,研究了烷基亚磷酸酯WESTON619在PP中的热氧稳定行为,并与芳基亚磷酸酯IRGAFOS168作了比较。The thermooxidative stabilization efficiency of alkyl-phophite WESTON 619 , made by Borg-Warner Chemical Corp ., U.S.A.. on PP was studied by measurements of both the processing stability and the oven ageing tests . Comparison was also made with IRGAFOS 168 , the aryl-phosphite made by CiBa-Geigy Corp . Switzerland.
