Our objectives were to develop a new chemical method for the polymerization of pyrrole. CuCl_2 dissolved in C_2H_5OH solvent is primarily used for the initiation polymerization of pyrrole. The polymers with different yield and conductivity were obtained by raring the initial concentration of Cu~(2+). The initial concentrations of Cu~(2+) varied from 1.2 ×10~(-4) mole to 6.48 ×10~(-3) mole Cu~(2+) with 2.16 ×10~(-2) mole pyrrole. The polypyrrole obtained was characterized with elemental analyzer, XPS, IR spectroscopy, Four-point probe and SEM.
