摘　　要：研究了经降温母粒改性的远红外聚丙烯的流变性能。试验结果表明 ,远红外聚丙烯与仅用降温母粒改性的普通纺丝聚丙烯的流变性能基本一致 ,但前者的粘流活化能比后者稍高。随着远红外微粉含量的增加 。The rheologic property of far infrared Polypropylene(PP) modified by chemical degradation agent was studied The experimental results showed that far infrared PP and normal PP modified only by chemical degradation agent were about the same in rheologic property for melts,but the far infrared PP was just over the normal PP in the energy of activation for flow With the increment of far infrared ceramic powder content,the non Newton index of the melts was reduced slightly

关 键 词：远红外纤维 聚丙烯 流变性能 改性
