摘要
对成孔剂（ＨＡ）－聚丙烯（ＰＰ）改性丙纶的流变行为进行了考察和研究。结果表明：共混ＨＡ使改性丙纶表现粘度下降；粘流活化能上升；流变指数值增大；挤出膨化现象变小，可纺性得到改善。
The rheological behaviour of HA-PP was studied in this paper.The experimental results showed that blended with HA the apparent viscosity of the mixed PP decreased and the adhesive fluid activation energy increased;the rheological index of the mixed PP increased and the bulked of spin decreased.The spinnability was improved.
