摘　　要：高含量的氘代聚合物的制备工艺在诸多领域具有重要意义,氘代乙炔接枝的聚乙烯是获取高含氘量聚乙烯衍生物的重要原料。采用一系列Sonogashira交叉偶联反应、自由基聚合以及水解反应制备了氘代乙炔接枝聚乙烯,并对中间聚合物以及目标聚合物从结构和性质上进行了表征,结果表明,它易溶于四氢呋喃、氯仿、丙酮,且在100℃开始明显失重。It is important for many fields to gain the preparation process of deuterated polymer with a high deuterium content. Deuterated acetylene grafted polyethylene is the main stuff to obtain such a polymer. By adoping sonogashira cross-coupling reaction, radical polymerization and hydrolyzation respectively, the deuterated acetylene grafted polyethylene were prepared. And its structure and properties were characterized. The results showed that it was easily soluble in tetrahydrofuran, chloroform and acetone, also 100℃ was the temperature of its initial weightlessness.
