| 摘 要： | 通过在聚丙烯（PP）中引入超支化聚合物形成共混体系，对超支化聚合物与聚丙烯共混后的性质进行了研究．结果表明，共混体系为非牛顿假塑性流体，随着超支化聚合物含量增大，表观黏下降，非牛顿流动指数降低，加工温度下降．超支化聚合物质量分数为2％时，拉伸强度上升约10％．

| Abstract: | The blending system containing hyperbranched polymer and polypropylene was prepared and characterized. The blend systems were non-Newtonian and shear-thinning fluid. The apparent viscosity, the non-Newtonian fluid index and processing temperature decreased with the increasing hyperbranched polymer content. The tensile strength was increased by about 10; when the content of hyperbranched polyamide was 2%. |
