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。TG曲线说明,丙炔醇/邻苯二甲酸反应产物是包含两种稳定性不同链段组成的共聚物结构。IR光谱证明了共聚物是邻苯二甲酸与丙炔醇均聚物的缩合产物。产物电导率的测量亦说明邻苯二甲酸的加入,并没有破坏聚丙炔醇的共轭体系,但共聚物的电导牢随邻苯二甲酸的含量增加而略有降低。SEM图显示了由于邻苯二甲酸的加入,使共聚物的表面结构更为致密。热分析结果表明,产物的热稳定性随邻苯二甲酸含量增加而提高。
Propargyl alcohol has been Copolymerized with phthalic acid by using (Ph_3P)_2. PdCl catalyst. The IR spectra of the copolymers demostrate that copolymers were polycondensation product of homopolymer of propargyl alcohol with phthalic acid. The measuring of conductivity of the copolymers also indicates that addition of phthalie acid did not destroy the conjugation system of homopolymer of propargyl 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.
