Abstract

      Polymers are employed in a variety of applications that may be harmful to the environment. As a result, the purpose of the research is to dismantle the mutated polymers by inexpensive materials to preserve the environment. To do this, an azole ring in 5-phenylazo salicalicaldehyde derivative was produced and put into a poly (vinyl chloride-vinyl acetate) (PVC-VA) chain by substitution process. The final product was created by adding 5-phenylazo salicalicaldehyde to the priority chemical. Under ultraviolet light irradiation in accelerated settings, the films' resistance to deterioration and IOH,ICO,IC=C were examined using Fourier-transform infrared spectroscopy, viscosity tests , and weight loss to follow the changes caused by UV radiation exposure. The azo compound significantly improved the photo degradation of PVC-VC polymer. When compared to the original polymer.
使用 5-苯基偶氮水杨醛衍生物光催化降解聚氯乙烯-醋酸乙烯薄膜
聚合物应用广泛,但可能对环境有害。因此,这项研究的目的是用廉价材料分解变异聚合物,以保护环境。为此,研究人员制作了 5-苯基偶氮水杨醛衍生物中的唑环,并通过置换工艺将其放入聚氯乙烯-醋酸乙烯(PVC-VA)链中。在优先化学品中加入 5-苯基偶氮水杨醛,即可制成最终产品。在紫外线加速辐照条件下,使用傅立叶变换红外光谱、粘度测试和失重法检测了薄膜的耐劣化性和 IOH、ICO、IC=C,以跟踪紫外线辐照引起的变化。偶氮化合物明显改善了 PVC-VC 聚合物的光降解。与原始聚合物相比
