Abstract

Pyrrole and N-methyl pyrrole were copolymerized by ceric ammonium nitrate (CAN) in aqueous solution. The resulting products were characterized by Fourier-transform infrared spectroscopy, UV-visible spectroscopy, and four-point probe conductivity measurements. The specific electrical conductivity of the copolymers can be increased depending on the mole ratio of pyrrole/N-methylpyrrole. The conductivities of copolymers are in the range of 10(-4)-10(-2) S cm(-1). Kinetic parameters were obtained by gravimetric determination of the copolymer and found to be dependent on [pyrrole](0.87) [N-methyl pyrrole](0.06) [CAN](0.11) [H2SO4](1.28) from gravimetric determination.
