聚乙炔聚乙炔polyacefylene乙炔的聚合物。结构为。有顺式聚乙炔和反式聚乙炔两种立体异构体。聚乙炔是最简单的聚炔烃。线型高分子量聚乙炔是不溶不熔,对氧敏感的结晶性高分子半导体,深色有金属光泽。顺式和反式聚乙炔的导电率分别为10-9和10-5/欧·厘米,如用碘、溴等卤素或BF3、AsF3等路易斯酸渗杂后,其导电率可提高到金属水平(约103/欧·厘米),因此称为合成金属及高分子导体。用齐格勒-纳塔催化剂,如TiCl4、TiCl3或Ti(OR)4与AlR3(R为烷基)组合催化剂可使乙炔直接聚合成膜,此外也可用钒、钴、铁等化合物如VO(CH3COO)2与Al(C2H5)3组成的催化剂体系聚合,聚合温度-78℃。用稀土催化剂(如环烷酸稀土和AlR3)时,则可在室温制得高顺式聚乙炔。聚乙炔是尚在开发研究中的新型功能高分子,已成功制成太阳能电池、电极和半导体材料,但尚未达到工业应用阶段。
