| 摘 要： | 采用回收聚对苯二甲酸乙二酯增粘以及加入增韧剂的方法，通过一步法熔融共混挤出得到了具有良好力学性能的聚碳酸酯／回收ＰＥＴ（ＰＣ／ＲＰＥＴ）合金。通过适当地增粘ＲＰＥＴ以及合适地选择增韧剂，只需加入２．５％的增韧剂 以得到力学性能与纯ＰＣ工程塑料相当的ＰＣ／ＲＰＥＴ共混合金。同时成本比纯ＰＣ大幅度下降。

| Abstract: | Melt blends of polycarbonate (PC) and recycled poly(ethylene terephthalate) (RPET) were prepared by one step extrusion. The selected PET chain extender and impact strength modifier were added to the system and synergistic effect was found. The toughness of PC/RPET blends could be greatly improved by adding only 2.5 wt% impact strength modifier. The mechanical properties of the toughened PC/RPET blends were comparable to those of pure PC but with lower cost. |
