【摘要】 本文第一章简要介绍了材料、高分子材料、金属有机高分子材料、金属有机缩聚高分子、金属有机配位聚合物和金属有机高分子磁性材料。并着重介绍了界面缩聚的定义、分类、特点以及影响缩聚物分子量的因素。 第二章介绍了以二茂铁为原料,合成了3种1,1’-二羰基二茂铁化合物,即1,1’-二乙酰基二茂铁,1,1’-二茂铁二甲酸以及1,1’-二茂铁二甲酸二甲酯。并利用1,1’-二甲酰氯二茂铁与八种二元胺发生界面缩聚生成八种含二茂铁的酰胺缩聚物,以1,l’-二甲酰二茂铁萘二胺缩聚物,1,1’-二甲酰二茂铁联苯二胺缩聚物,1,1’-二甲酰二茂铁间苯二胺缩聚物,1,1’-二甲酰二茂铁对苯二胺缩聚物与Cu、Co、Ni、Zn反应,生成九种配位聚合物。 第三章论述了对3种1,1’-二羰基二茂铁化合物用IR、UV、1H NMR、TG、ESR、XPS及60Co-γ射线对其化学性质的影响进行系统表征。同时,对合成的1,1’-二甲酰二茂铁联苯二胺缩聚物和1,1’-二甲酰二茂铁邻苯二胺缩聚物用元素分析、IR、1H NMR、TG-DTA、GPC及XPS对其化学与物理性能进行分析。并用X光衍射研究了聚1,1’-二甲酰二茂铁对苯二胺Zn配合物。 研究结果表明,DAF与FDC的规模化生产是成功的,辐照可提高3种1,1’-二羰基二茂铁化合物的热稳定性约10%~15%。1,1’-二甲酰二茂铁联苯二胺缩聚物和1,1’-二甲酰二茂铁邻苯二胺缩聚物为中等耐热性,其热分解机理十l声月川少巾范大学可!I毕业么仑文分tll似。(;l’C的测定表明,一L述两种缩聚物在ZnCI:催化作用};的M。及M*均较无催化剂卜的杆!应缩聚物大1 .5倍左右。其中,1,l’一几甲酞二茂铁邻苯二胺缩聚物的分子量分布曲线呈现三重峰,表明在高转化率时发生大分子链转移后生成带支链的高分子,其多分散性也较大。xf)s能谱表明,l,l’一二甲酞二茂铁联苯二胺缩聚物和l,1’一二甲酞二茂铁邻苯二胺缩聚物的F。二/:峰位在7()8洲附近,却未乃通常二茂铁和聚乙烯基二茂铁在711.0洲附近的肩峰,表明其二茂铁基团相当稳定。

【Abstract】 In chapter 1 of this paper, simply introduces material polymer materials, organometallic polycondensate ,organometallic coordination polymer and organometallic polymeric magnetic materials. Detailedly introduces definition classification and character of interfacial polycondensation and influential factors of polycondensate molecular weight.In chapter 2, introduces synthesis of three 1,1’-dicarbonylferrocene compounds. Uses l,r-diformacylferrocene chloride and eight diens to synthesize eight ferrocene acylamide polycondensates. Uses 1,1 ’-diformacylferrocene-naphthylene-diamine polycondensate,1,1’-diformacylferrocenebiphenyldiamine polycondensate, l,1’-diformacylferrocenemetaphenylenediamine polycondensate and 1,1’-diformacylferrocene-p-phenylenediamine polycondensate with Cu, Co, Ni and Zn to synthesize nine coordination polymers.In chapter 3, the three 1,1’-dicarbonylferrocene compounds’ properties are systennically characterized by IR, UV,1HNMR, TG, ESR, XPS and the infrared difference spectrum before and after irradiation 1,1’-diformacyl-ferrocenebiphenyldiamine and 1,1’-diformacylferrocene-o-phenylenedamine polycondensates’ chemical and physical properties are characterized by elemental analysis,IR,1HNMR, TG-DTA, GPC and XPS.Results show that the commercial scale production of DAF and FDC issuccessful. Thermal stability of the three 1,1’-dicarbonylferrocene compounds can be enhanced 10%~15% by irradiation. 1,1’-difonnacylferrocenebiphenyldiamine polycondensate and 1,1’-diformacylferrocene-o-phenylenediamine polycondensate are middle heat resistant, their thermal decomposition mechanism are similar. Mn and Mw of the two polycondensates which are catalysed by ZnCl2 are about 1.5 time than the polycondensates which have no catalyst. Molecular weight distribution curve of 1,1’-diaformacylferrocene-o-phenylenediamine polycondensate has triplet and polydispersity is a little large. It should be pointed out that the Fe2P3/2peak appears basically near Fe2+ characterizing 708eV in XPS of the two polycondensates, this means that the ferrocene group is rather stable in the polycondensates.
