Synthesis, characterization and electrical conductivity of new poly (azomethine ester)s from hydroxy acids
Two new poly (azomethine ester)s were synthesized by direct polycondensation of 4′-hydroxybenzalaniline-4-carboxylic acid (1) and 4′-hydroxy-3′-methoxybenzalaniline-4-carboxylic acid (2) using dichlorophenylphosphine at 140 °C in DMF solvent containing LiCl. Polymers were precipitated by pouring the...

Summary: | Two new poly (azomethine ester)s were synthesized by direct polycondensation of 4′-hydroxybenzalaniline-4-carboxylic acid (1) and 4′-hydroxy-3′-methoxybenzalaniline-4-carboxylic acid (2) using dichlorophenylphosphine at 140
°C in DMF solvent containing LiCl. Polymers were precipitated by pouring the reaction mixture into water. Monomers and polymers were characterized by viscosity, IR,
1H NMR and TGA. One of the poly (azomethine ester) derived from 4′-hydroxybenzalaniline-4-carboxylic acid (1) when blended with polyaniline/HCl, polyaniline/NH
4OH and polyaniline shows conductance in the range 5.6
