用(Ph_3·P)_2·PdCl_2催化丙炔氯均聚,得到褐色或黑色产物。研究了聚合条件对聚合反应的影响。聚合产物的红外光谱分析表明它是丙炔氯的均聚物。元素分析结果显示聚合物除大部分链段为-C=C- CH_2Cl外,还有部分其它链段存在。聚合物的电导率为10~(1)S·m~(-1)。TG分析表明丙炔氯聚合物较丙炔醇易受热分解。GPC测得聚合物的数均相对分子质量为1350。
The propyne chloride was homopolymerized by (Ph_3P) _2PdCl2 to give brown or black product. The effects of polymerization conditions on the polymerization were investigated. Infrared spectroscopy of the polymerized product showed it to be a propyne chloride homopolymer. The results of elemental analysis showed that most of the polymer chains existed in addition to -C = C- CH_2Cl, and some other segments existed. The conductivity of polymer is 10 ~ (1) S · m ~ (-1). TG analysis shows that propynyl polymer is more susceptible to thermal decomposition than propynol. The number average molecular weight of the polymer measured by GPC was 1,350.
