Synthesis and Characterization of new diamines based on bis( 5-cyclopentadienyl) iron and related poly(amide ether amide)s

Synthesis and characterization of bis( 5-cyclopentadienyl)iron-containing main-chain poly(amide ether amide)s are reported in this research. Novel diamines were prepared by the condensation reaction of 1,1’-ferrocenedicarbonyl chloride with 2,6-bis(4-minophenoxy)pyridine(AP) and 2,6-bis(5-amino-1-naphthoxy)pyridine(AN). A series of with various diacid chlorides in N-methyl-2-pyrrolidone(NMP) using trimethylchlorosilane (TMSCl) as activating agent. The monomers and polyamides were characterized and inherent viscosity, solubility, thermal stability and behavior, flame-retardancy, and crystallinity of the polymers were studied. The polymers showed good heat-resistant, flame-retardancy, and also improved solubility in polar aprotic solvents
