| 摘 要： | 对回收聚丙烯（RPP）进行增韧改性，制备回收聚丙烯，回收胶粉（RPP/WRP）和回收聚丙烯／热塑性弹性体POE（RPP／POE）共混材料，研究两种共混材料的韧性、力学、热、流变性能和形态。结果表明，RPP／WRP改性体系有较好的韧性和耐热性，较高的硬度，属于假塑性流体，回收胶粉可以部分替代POE作为某些制品的增韧剂。

| Abstract: | Reused polypropylene （RPP） was toughed to made RPP/WRP and RPP/POE blends. The toughness, mechanical, thermal, rheological properties and morphology of the blends were studied. The results showed that RPP/ WRP blend had high toughness, better thermal resistance and high hardness. RPP/WRP blend was pseudoplastic fluid. POE can partly be substituted by WRP for toughening some products. |
