Özet
Poly(m-aminophenol) (PMAP) and poly(m-aminophenol)-succinat compound (PMAP-Suc) containing ester bridge were synthesized in this study. PMAP were synthesized by chemical oxidative polymerization of m-aminophenol (MAP) in HCl medium with ammonium peroxydisulphate (APS) as an initiator at different temperatures. The optimum polymerization conditions (temperature: 25 degrees C, reaction time: 4 h, normalized MAP/APS ratio, k: 0.625 and mol of MAP/mol of APS, r: 0.5) of PMAP were determined. PMAP was esterified in N-methyl pyrrolidone by using solution of succinic acid as cross-linking agent and concentrated sulphuric acid as catalyst under appropriate ambient conditions. The general scheme of esterification and cross-linking reaction for PMAP is proposed. These reactions were also evidenced by spectroscopic, thermal and surface morphology as well as structural characteristics relationship of macromolecules. The structures of PMAP and PMAP-Suc were characterized by solubility test, FTIR, H-1 NMR and C-13 NMR, UV-vis spectroscopy, thermal (TGA-DTA) and SEM analyses.
