摘要：

Copolymers of o-lm-toluidine with o-lm-amino benzoic acid have been synthesized by chemical polymerization using inverse emulsion pathway and characterized by a number of techniques including UV-Vis, FT-IR, FT Raman, EPR and NMR spectroscopies, thermal analysis and conductivity. The solubility of the copolymers in organic solvents increases with increase in the amount of amino benzoic acid in the feed. The copolymers synthesized at room temperature show relatively higher conductivity and are obtained in higher yield compared to those synthesized at 0 and 60 degreesC. The spectral studies have revealed restricted conjugation along the polymer chain. The effect of -COOH substituent on the copolymer structure is discussed.
