用界面缩聚法合成主链含二茂铁的聚酰胺、聚脲和聚酯

Synthesis of Ferrocene-Containing Poiyanlides,Polyureas and Polyesters in Their Backbones by the Interfacial Technique

最近,作者和Lenz等用阳离子型聚合反应研究了一系列含Fe、Sn和Ti的异丙烯基二茂金属聚合物,证明了这些金属有机聚合物有可能发展成兼具光、电、声、磁、耐热和抗辐射的特种高分子材料。近年来,Carraher等用界面缩聚法合成了许多ⅣA,ⅣB和ⅤA族的金属有机聚合物.

Monomers,i,1’-bis(β-aminoethyl)ferrocene(1)and 1,1,-bis(β-hydro-xyethyl)ferrocene were synthesized starting frpm ferrocene via acetylation,hydrolysis,esterification,cyanidation and reduction,yields obtained were 73%and 98%,respectively.Monomer(1)then,reacted with diacid chlorides as well as with diisocyanates,and monomer(2)reacted with terephthaloyl chloride,leading to ferrocene-containing polyamides,polyureas and polyesters in their backbones under the interfacial polymerization condition.TG analysis of the ferrocene-containing polyamide,in contrast,with the poly urea and polyester,showed weight loss only 1.0 to 1.5%at 300℃and 3.0 to 6.0%at 400℃,respectively.
