We recently reported the synthesis of the monomer l,l'-bis(/3-aminoethy1)ferrocene (1) and its polymerization with diacid chlorides via interfacial condensation techniques to form polyamides.' CH ,CH,NH ,
?Fe 1In the present study, it was of interest to determine the relative reactivities of hexamethylenediamine and 1,l'-bis( P-aminoethy1)ferrocene (1) vis-a-vis sebacoyl chloride. Monomer 1 does contain aliphatic amine functional groups which are not hindered in their reactivities, sterically or electronically, by the ferrocene nucleus.' However the diffusion of 1 could be affected by its relative bulk and rigidity compared to the greater flexibility of the methylene groups in hexamethylenediamine.Korshak and coworkers' had reported the formation of mixed polyamides by interfacial polymerization with mixtures of various diamines. Interfacial polymerization was conducted with adipoyl chloride and mixtures of ethylenediamine, hexamethylenediamine, or m-phenylenediamine in a benzenewater system. These investigators demonstrated that mixed polyamides and not mixtures of homogeneous products were formed. In the first stages of the reaction the composition of the mixed polyamides found a t the interface differed from the composition of the original mixture, and was determined by the diffusion of the diamines into the organic phase. The reactivities of the diamines were considered to be of only secondary importance.
RESULTS AND DISCUSSIONS
Blends of 6,lO Nylon and FcJO Organometallic PolyamideAt the outset it should be clarified, that by analogy to the nomenclature for nylons, it was decided to term the polyamide obtained from sebacoyl chloride and 1,l'-bis( /3-aminoethy1)ferrocene as Fc,lO organometallic polyamide (nylon).
