摘　　要：在0℃和弱酸催化下利用乙二醛和乙二胺合成聚合长链席夫碱,再用FeCl3掺杂上述中间产物制得聚合长链席夫碱铁盐。阐述了聚合长链席夫碱的合成机理,分析了合成温度对反应的影响以及掺杂剂用量对产物电导率的影响,并表征产物的结构与组成。当掺杂剂FeCl3的用量达到饱和掺杂率时,该方法制得的聚合长链席夫碱铁盐,其电导率为3.02×10-3S/cm。A polymeric long-chain schiff base ferric salt was prepared by ferric chloride doping polymeric long-chain schiff base which was synthesized from glyoxal and ethylene diamine at 0℃ with weak acid as catalyst. The synthetic mechanism of that schiff base was discussed, and the effects of synthetic temperature on the reaction and adulterant contents on the conductivity of production were analyzed. The structure and composing of production were characterized. The conductivity of synthzised Schiff base can be 3.02×10^- 3 S/cm after FeCl3 adulterant content was at a saturated doping rate.
