摘要(Abstract)：

以乙烯-马来酸酐共聚物(ZeMac)作为反应性相容剂,利用熔融纺丝法制备了聚碳酸亚丙酯(PPC)-聚乳酸(PLA)共混纤维。通过傅里叶变换红外光谱仪、热重分析仪、差示扫描量热分析仪、纤维强伸度仪等分别研究了共混纤维的分子结构、热稳定性、相容性及力学性能。结果表明:PLA的引入较大地提高了PPC的力学性能,加入少量的ZeMac可以有效地改善PPC的热稳定性,同时也能够提高共混体系的相容性。当PPC-PLA与PPC-PLA-ZeMac体系组分质量比分别为70/30和70/30/0.7时,其抗拉强度分别为11.23 MPa和20.83 MPa,较未改性的PPC分别提高了6.5倍和12.1倍,同时还能保持较高的断裂伸长率。该项研究为完全可生物降解PPC熔融共混纤维的工业化提供了可能性。
The blend fibers of poly(propylene carbonate) and polylactic acid(PPC-PLA) with ethylene-maleic anhydride copolymer(ZeMac) as a reactive compatibilizer are prepared by melt spinning. The molecular structure, thermal stability, miscibility and mechanical properties of the blend fibers are investigated by Fourier transform infrared spectroscopy(FTIR), thermal gravimetric analysis(TGA), differential scanning calorimetry(DSC) and fiber strength and elongation tester. The results show that the mechanical properties of PPC can be greatly improved by introduction of PLA and the thermal stability of PPC as well as the compatibility of the blends can be effectively improved by adding a small amount of ZeMac. When the components of PPC-PLA and PPC-PLA-ZeMac are 70/30 and 70/30/0.7, their tensile strength are 11.23 MPa and 20.83 MPa which are 6.5 and 12.1 times respectively compared with PPC fiber, while maintaining high elongation at break. This study offers a possibility of industrial application to biodegradable PPC melt blend fibers.
