【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。更多还原

【Abstract】 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.更多还原
