ABSTRACT: Chemical copolymerization of aniline with o-anthranilic acid in aqueous 1 M HCl was carried out at
different molar ratios of aniline and o-anthranilic acid, and was characterized by FTIR and UVVisible
spectroscopy, elemental analysis and electrical conductivity. From FTIR and UV-Visible spectroscopy,
we observed that o-anthranilic acid had been introduced into the polymer chain successfully.
The percent yield of o-anthanilic acid copolymer with aniline decreases as the percent of
aniline increases. An increase in the % C can be observed as the amount of o-anthranilc acid in the
copolymer decrease or the amounts of aniline increase. Copolymerization of aniline with o-anthranilic
acid would improve the resulting polymer via increasing the molecular weight and the conductivity
as well.
