| 摘 要： | 熔融挤出制备了3种大分子相容剂改性纳米CaCO3/PP复合材料,利用FTIR研究了复合材料的光氧化行为。结果表明,纳米CaCO3促进了PP的光氧化降解,但不改变PP的光氧化反应机理。不同相容剂对纳米CaCO3/PP复合材料光氧化行为有不同的影响,马来酸酐接枝乙烯-辛烯共聚物(POE-g-MA)和马来酸酐接枝乙烯-醋酸乙烯酯共聚物(EVA-g-MA)促进纳米CaCO3/PP复合材料的光氧化降解,而马来酸酐接枝聚丙烯（PP-g-MA）降低纳米CaCO3/PP复合材料的光氧化速率,认为与不同相容剂对PP结晶形态和结晶度有不同影响有关。

| Abstract: | The CaCO3/PP composites were modified by three kinds of compatibilizers. The photo-oxidative behavior of PP-base composites was investigated using FT-IR. The results indicated that the photo oxidation mechanism of PP was not modified by nano-CaCO3, but the rate of the oxidation dramatically enhanced.The addition of macromolecular compatabilizers had different effect on the photo-oxidative de gradation of nano CaCO-3/PP composites. Addition of POE-g-MA and EVA-g-MA increased the rate of photo-oxidation of nano-CaCO3/PP composites, while addition of PPg-MA reduced the rate of photo-oxidation of nano CaCO3/PP composites. These properties were probably dependent on the morphology and crystallinity of PP in the composites. |
