中文摘要: 采用溶液法制备了聚（氯乙烯-醋酸乙烯酯）（PVCAc）与热塑性聚醚型聚氨酯(TPU)的共混膜(PUV)。通过FT-IR和DSC对膜的形态和相容性进行了研究。与聚氯乙烯(PVC)相比，PVCAc与TPU的相容性明显增强。将PUV膜浸没于H2O2-CoCl2溶液中25 d进行加速氧化实验，结果表明：PUV膜的氧化稳定性优于TPU和TPU/PVC的共混膜(PUC)。此外，PUV膜的力学性能明显高于PUC膜。
Abstract:Poly(vinyl chloride-co-vinyl acetate) (PVCAc) / thermoplastic polyether polyurethane (TPU) blend films (PUV) were prepared via solution casting. The morphology and miscibility of PUV films were studied by FT-IR and DSC. Results show that PVCAc is more miscible with TPU than poly(vinyl chloride). Accelerated oxidation test was carried out by immersing the blend films in H2O2-CoCl2 solution for 25 d. The oxidative stability of PUV films is significantly enhanced in comparison to that of TPU and TPU/PVC blend films (PUC).Furthermore, the mechanical properties of PUV films are higher than those of PUC films.
