| 摘 要： | 研究了两亲性超支化聚（胺-酯）（A-HPAE）对PVC／PP共混体系的增容作用，讨论了其用量对PVC／A-HPAE／PP共混体系力学性能和复数黏度的影响。结果表明，在PVC／PP共混物中加入2份（质量份，下同）A-HPAE时，能很好地改善共混体系的相容性，使共混物的拉伸强度和断裂伸长率分别达到26．18mPa和18．72％，比未加的分别提高了107．67％和34．68％；共混体系的绝对复数黏度随着A-HPAE用量的增大而降低；扫描电子显微镜分析表明，A-HPAE增强了PVC和PP之间的界面黏结作用，减小了共混体系中分散相的尺寸。

| Abstract: | The compatibilization effect of amphiphilic hyperbranched poly(amide-ester)(A-HPAE)on the mechanical and rheological properties of PVC/PP blends was investigated.The blends containing 2 phr A-HPAE increased the tensile strength and elongation at break by 26.18 MPa and 18.72%,re- spectively,based on neat blends.With the increase of content of A-HPAE,the complex viscosity of the blends decreased.The scanning electron microscopy(SEM)indicated that A-HPAE reduced the size of disperse phase in the blends indicating the compatibilization. |
