【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.更多还原
