Abstract

We have investigated a novel monomer having two pendant phenyl imido groups for preparing new aromatic polyamides. Novel polyamides were synthesized by direct polycondensation reaction with the N,N′-diphenyl-2,3,5,6-diimido benzene-1,4-dicarboxylic acid chlorine (PIBAC) and some aromatic diamines such as p-phenylene diamine, 4,4′-oxydianiline and 4,4′-methylene dianiline. Inherent viscosity of the resulting polyamides are in the range 0.20-0.85 dl/g range. The decomposition temperature of these polyamides are ranged from 350-450°C and the ash contents of them orders MDA > ODA > SDA according to the kinds of the diamines used. In addition, the solubility of these polyamides is very good in aprotic solvents such as DMAc, NMP, and DMF. A transparent flexible and tought film was cast.
