【摘要】 <正> 由于聚乙炔具有导电性能,近年来,人们对聚炔烃化学引起了广泛的重视。1979年Yamabe等设想用氟原子取代聚乙炔上的氢原子,期望得到对氧稳定的聚炔烃。最近Bubner等报道了用正丁基锂和氯化钯在DMF中催化三氟申基乙炔得到稳定的低分子量线型聚合物。当用碘蒸气掺杂后,其电导率σ_max达9.510^-5-1cm^-1。另有文献报道更多还原

【Abstract】 Polymerization of perfluorobutyne-2 catalyzed by π-bis(benzene)chromium(0) in basic medium affords a lustrous black polymer with an average molecular weight in the range of 1200-1500. It decolorizes potassium permanganate in acetone solution. IK and TJV spectra show that it possesses conjugated double bonds. Its conductivity is found to be τ=8.8×10-11Q-1cm-1. Thermoanalysis illustrates that the polymer is thermally stable in air below 150℃.更多还原
