Abstract

Five Schiff bases derived from melamine have been used as efficient additives to reduce the process of photodegradation of poly(vinyl chloride) films. The performance of Schiff bases has been investigated using various techniques. Poly(vinyl chloride) films containing Schiff bases were irradiated with ultraviolet light and any changes in their infrared spectra, weight, and the viscosity of their average molecular weight were investigated. In addition, the surface morphology of the films was inspected using a light microscope, atomic force microscopy, and a scanning electron micrograph. The additives enhanced the films resistance against irradiation and the polymeric surface was much smoother in the presence of the Schiff bases compared with the blank film. Schiff bases containing an ortho-hydroxyl group on the aryl rings showed the greatest photostabilization effect, which may possibly have been due to the direct absorption of ultraviolet light. This phenomenon seems to involve the transfer of a proton as well as several intersystem crossing processes.

摘要

五种由三聚氰胺衍生的席夫碱已被用作高效添加剂,以减少聚氯乙烯薄膜的光降解过程。使用各种技术研究了席夫碱的性能。含有席夫碱的聚氯乙烯薄膜用紫外线照射,并研究了它们的红外光谱、重量和平均分子量的粘度的任何变化。此外,还使用光学显微镜、原子力显微镜和扫描电子显微镜检查了薄膜的表面形貌。添加剂增强了薄膜对辐射的抵抗力,并且与空白薄膜相比,在存在席夫碱的情况下,聚合物表面更加光滑。在芳环上带有邻位羟基的席夫碱表现出最大的光稳定化效果,这可能是由于直接吸收了紫外线。这种现象似乎涉及质子转移和几个体系间交叉过程。
