摘要
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 polymerization of propargyl chloride catatyzed by (Ph_3P)_2PdCl_2 gives brown or black powder polymers. The polymers are partially soluble: in THF. with molecular weight-1350. IR spectra of product show they are the polymer of propargyl chloride. The conductivity of polymer is about 1×10^(-10) S·m^(-1). The composition of polymers has been studied with Elemental Analysis, and the heat stabilities of them have also been studied.
