| 摘 要： | 本文研究了苯乙炔在WOBr_4催化剂作用下的聚合行为,并对催化聚合机理进行了探讨。所得聚合物是可溶可熔的褐红色固体,其最高分子量为1830(M_n)。WOBr_4催化剂具有催化剂用量少(2/100),聚合反应时间短(10秒钟),产物收率高(80％以上)等特点。结构分析结果表明,WOBr_4催化聚苯乙炔具有顺-反式微观结构。

| Abstract: | A new kind of catalyst, WOBr4, which can be used in the polymerization of pheny-lacetylene (PhA), has been synthesized. The polyphenylacetylene (PPhA) obtained using WOBr4as catalyst is soluble and fusible and brown-red and has 1830 (Mn). The structure analysis of PPhA shows that the polymer has cis-transoidal structure and the reaction mechanism is via complex catalysis. |
