摘　　要：用WCl6-Ph4Sn催化下聚合生成了双取代乙炔衍生物,在产物的红外光谱上,2 205 cm-1处C-C键的伸缩振动特征吸收峰消失及1 621 cm-1处C=C双键的生成,这些特征变化证明了聚合反应的发生。单体苯丙炔酸通过肉桂酸的加成消去反应制得,单体C6H5C-CCOO(C6H4)OCOCH2CH3则通过苯丙炔酸和对羟基苯甲酸乙酯酯化制得,通过红外光谱、元素分析、XRD、紫外光谱和荧光光谱对聚合物结构和性质进行了表征,结果显示,这种共轭聚合物在光激发下能发出蓝光且聚合物能溶于普通的有机溶剂。A disubstituted acetylene was polymerized into poly （phenylpropiolic acid-ethyl-p-hydroxybenzoate） with WCl6-Ph4Sn as catalyst and toluene as solvent. The disappearance of the characteristic vibrations at 2 205 cm^-1（ C≡C ）and the appearance of the characteristic vibrations at 1 621 cm^-l（ C=C ） indicated the polymerization of monomers. The monomer phenylpropiolic acid was obtained by addition and elimination reaction from cinnamic acid, the monomer C6H5 C≡C COO （C6H4 ）OCOCH2 CH3 was syn- thesized by esterification from phenylpropiolic acid and ethyl p-hydroxybenzoate. The structures and properties of PAs were confirmed by IR, UV, XRD. The polymer shows green light under light excitation and is soluble in common organic solvents.
