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。
This paper reports the copolymerization of propargyl alcohol and phthalic acid in the presence of (Ph_3P) _2 · PdCl_2. The product of the copolymerization was confirmed by IR to be a condensation product of homopolymer of phthalic acid and propynyl alcohol. The product conductivity shows that the addition of phthalic acid does not destroy the conjugated system of polyallylene alcohol, but the conductivity of copolymer decreases with the increase of phthalic acid content. The addition of phthalic acid, the copolymer surface structure is more dense. The thermal stability of the product increased with the increase of phthalic acid content.
