Abstract :In here, the nonisothermal decomposition kinetics of co-polymers based phenothiazine was present-ed. For this, firstly, 3, 7-di-2-thienyl-10H-phenothiazine insert ignore into journalissuearticles values(TF); was prepared via an optimized Suzu-ki–Miyaura cross-coupling reaction. After monomer insert ignore into journalissuearticles values(TF); characterization, the copolymerization re-actions with EDOT and thiophene were performed by the electrochemical technique. The molecular masses of the co-polymers were found by gel permeation chromatography insert ignore into journalissuearticles values(GPC); analysis. Thermal characterizations of the resulting polymers were conducted by thermogravimetric analyses. The thermal decomposition kinetics of the resulting polymers was also performed. For this, the kinetic methods insert ignore into journalissuearticles values(Tang, FWO, KAS, Kissinger, and Friedman); based on the multiple heating rates were used. Several kinetic parameters related to the decomposition kinetics of the solid-state were revealed.
