摘要： 聚乙快的不稳定性及难以加工影响了其应用[1].最近,Naarmann[2]通过陈化在硅油中的Ti(OBu)4-AlEt3催化体系及加入不同量的Li-(n-Bu)制得了拉伸后电导率达105S/cm的聚乙炔膜,此膜的电导和形态在空气中几个月几乎不发生改变.我们曾报导用加热的甲苯-Ti(OBu)4--AlEt3催化体系合成高性能聚乙炔膜[3].本文进一步讨论不同溶剂对高性能聚乙炔(HPPA)合成及性能的影响.

Abstract: Acetylene polymerized by a heat aged mixture of Ti(OBu)4-AlEt3 in various solvents(alkane and aromatic hydrocarbon)yields a high performance polyacetylene film (HPPA).Being doped with iodine, the films showed an electrical conductivity of 103 S/cm at roomtemperature. The value was over 104 S/cm after stretching of the film. The HPPA filmswere high compact and stable in air and composed of relatively ordered piling up of fibrils.Its apparent density and permeability of N2 were 0.80g/cm3 and 3.2?10-11 Jcm3 (STP)/cm2·s·cm Hg,respectively. The results of IR, TEM and X-ray diffraction indicated that the filmswere high crystalline and had 65-85% of cis-PA and 20-100 nm of fibre diameter.
