Copolymers of 2-methoxyaniline with 2- and 3-aminobenzenesulfonic and 2- and 3-aminobenzoic acids: Relationships between the polymerization conditions, structure, spectroscopic characteristics and conductivity

Popis výsledku v původním jazyce

The effect of the reaction conditions - feed monomer ratio, oxidant/monomers ratio, reaction time, reaction temperature, T, and HCl concentration - on the structure, conductivity and spectra of partly self-doped copolymers of 2-methoxyaniline (OMA) withthe anilinic acids. (ANIA) 2- and 3-aminobenzoic and the 2- and 3-aminobenzenesulfonic acids was studied using ICP-AES/elemental analysis, size exclusion chromatography, NMR, FT-IR, UV-vis and impedance spectroscopy. The molar fraction of the OMA units,F1, in a P(OMA/ANIA) copolymer always exceeded the OMA fraction, f1, in the feed monomer mixture since the OMA is much more reactive than any ANIA due to the electron-donating effect of the methoxy group. Increasing f1 consistently increased the yield and the molecular weight (MW) of the P(OMA/ANIA), and with an under-stoichiometric amount of oxidant or a shortened reaction time this favored the incorporation of the OMA into the copolymer chains. Increasing the acidity of the reaction mi
