聚苯乙炔的合成及其表征——用无水AlCl₃和(Ph₃P)₂PdCl₂二种催化剂

摘要:

本文用无水AlCl₃和 (Ph₃P)₂PdCl₂二种催化剂催化苯乙炔聚合，得到共轭聚合物聚苯乙炔(PPA)。对PPA的微结构分析表明：用无水AlCl₃催化苯乙炔，得到顺-反式 PPA；用(Ph₃P)₂PdCl₂催化苯乙炔得到反-顺式PPA。因此，作者认为用无水AlCl₃ 催化苯乙炔聚合时可能按络合催化机理反应；用(Ph₃P)₂PdCl₂催化苯乙炔聚合时可能按易位催化机理反应。

Abstract:

In this paper，the polyphenylacetylene(PPA) is synthesised by the polymerization of phenylacetylene with two kinds of catalysts，anhydsous AlCl₃and (Ph₃P)₂PdCl₂. Using anhydrous AlCl₃ as catalyst，the cis-trans PPA is obtained. And using (Ph₃P)₂PdCl₂,the trans-cis PPA is found. Therefore，the polymerization of phenylacetylene may follow complex catalysis mechanism when anhydrous AlCl₃ is used as a catalyst and it may follow metathesis catalysis mechanism when (Ph₃P)₂PdCl₂ is used.

Keywords: phenylacetylene,polyphenylacetylene,(Ph₃P)₂PdCl₂
