摘　　要：报道了用EVA对丙纶物理改性的实验研究,论述了这种改性丙纶的流变性能。由于引入极性基团,破坏了丙纶的高规整性导致的高度结晶,并且通过部分溶出改性剂生成微孔,从而大大改善了丙纶纤维的吸湿性能和导电性能。共混体系的粘度对温度和压力都有明显的依赖性,改性剂EVA的加入量不同影响了共混体系的粘度,在纺丝过程中值得注意。This paper reports the experimental study of modifying polypropylene by EVA blending. The rheological behavior of this product is detailed. The highcrystalization of polypropylene deduced by its highregularization is Owing to introducing polarized element, using the capillary viscosimeter, we had a rheological experiment on EVA-PP blend system, which show us the blend system apparent viscosity has good reliability on temperature and pressure and the different mixed quantum of modifying agent(EVA) influenced the blend system viscosity, on which we should have an attention in the spinning process. 
