摘要
本文报导了(Ph_3P)_2·PdCl_2存在下的丙炔醇与邻苯二甲酸的共聚合反应。并通过IR证明了共聚产物是邻苯二甲酸与丙炔醇均聚物的缩合产物。产物电导率说明邻苯二甲酸的加入,并没破坏聚丙炔醇的共轭体系,但共聚物的电导率随邻苯二甲酸含量的增加而降低。邻苯二甲酸的加入,共聚物的表面结构更为致密。产物的热稳定性随邻苯二甲酸含量的增加而提高。
Propargyl alcohol has been Copolymcrized with phthalic acid by using (Ph_3P)·PdCl_2 catalyst. The IR spectums of the copolymer demostrate that the copolymers were polycondesation product of homopolymer of propargyl alcohol with phthalic acid. The measuring of conductivity of the coolymers also indicate that addition of phthalic acid has not destroled the conjugation system of polypropargyl alcohol. Thermal analysis of the copolymers shows that the heat oxidation stability of the products was increased with increasing of the content of phthalic acid.
