【摘要】 <正> 炔类聚合物由于具有长链π体系的结构特点,理论上可作为结构型导电聚合物,这一领域的研究工作正在迅速展开。 1,4-丁炔二醇(BD)可用PdCl2,ZnCl2,(Ph3P)2PdCl2等多种催化剂催化聚合,得到长链共轭的聚(1,4-丁炔二醇)(PBD)。苯乙炔(PA)可用热聚合,光聚合、电聚合、自由基聚合、等离子体聚合、催化聚合等聚合方法,得到长链共轭的聚苯乙炔

【Abstract】 The conjugative poly(1,4-butynediol) (PBD) was synthesized using Mods, Cd(NO3)2. 4H2O and (Ph3P)2PdCl2 catalysts respectively. The behaviours of copolymerization of pheny-lacetylene (PA) and butynediol (BD) were investigated by (Ph3P)2PdCl2 catalyst. When PA/ BD≥1 (mole ratio), the copolymers are soluble and fusible. When PA/BD=1, the copolymers obtained can be separated into two coponents, one is soluble and fusible, another insoluble and infusible. When PA/BD≤1, the copolymers are insoluble and infusible. According to IR spectra of homopolymers and copolymers, the metathesis catalysis mechanism was proposed.
