摘　　要：以二茂铁和丙酮为起始原料,经一系列反应制得6-异丙烯基双二茂铁基丙烷和6-(α-苯乙烯基)双二茂铁基丙烷及相应的均聚物,通过红外光谱、元素分析、核磁共振氢谱对单体和聚合物的结构进行了表征,测定了聚合物的差热热重,对聚合物的热性能做了初步研究。结果表明,聚合物骨架中金属元素的存在,将显著提高聚合物的热稳定性;且分子结构中含有苯环的聚合物,其热稳定性高于不含苯环的聚合物。6-isopropenyl bisferrocenylpropane, 6-（a-benzenevinyl） bisferrocenylpropane and their corresponding homopolymers were obtained from ferrocene and acetone through a series of reactions. The compounds and homopolymers were characterized by elemental analyses, IR spectra and 1H NMR spectra. The thermal stabilities of the homopolymers were studied using DTA-TGA. The results showed that the thermal stabilities of the ho- mopolymers containing ferrocenyl groups were obviously increased, the homopolymers maintained unchanged until approximately 300℃ In addition, the introduction of phenyl group improved the thermal stability of the polymer.
