The electrochemical properties of poly(alpha-methylbenzyl dipropargylamine) was studied by cyclic voltametry. Poly(alpha-methylbenzyl dipropargylamine) was prepared by the cyclopolymerization of alpha-methylbenzyl dipropargylamine in high yield. The photoluminescence peaks of the present polymer was observed at 443 nm corresponding to the photon energy of 2.80 eV. The cyclovoltamograms of the polymer exhibited the irreversible electrochemical behaviors between the doping and undoping peaks. It was found that the kinetics of the redox process of poly(MBDPA) might be mainly controlled by the electron transfer process from the experiment of the oxidation current density of poly(MBDPA) versus the scan rate.
