本文研究了用 PVC 改性的聚丙炔醇的合成与性能。测定了聚合产物的组成曲线。热分析表明。少量的 PVC 可大大提高改性聚合物的起始失重温度和分解温度:红外光谱显示,聚合时 PVC 含量越高,聚合产物中共轭链段的长度越短:扫描电镜图像显示.PVC 改性聚合物的表面结构比丙炔酵均聚物要致密。
In this paper, the synthesis and properties of poly (propynyl alcohol) modified with PVC were studied. The composition curve of the polymerization product was measured. Thermal analysis shows. A small amount of PVC can greatly improve the initial weight loss temperature and decomposition temperature of the modified polymer: the infrared spectrum shows that the higher the content of PVC during polymerization, the shorter the length of the conjugated segment in the polymerization product: the SEM image shows that the PVC modified polymer The surface structure of the material is more dense than the propyne homopolymer.
