Thermal decomposition kinetics of glycine complexes with light rare earth bromides was studied under non-isothermal conditions by DSC technique. Their kinetic parameters(activation energy E, pre-expontial factor A) were obtained from the analysis of the DSC results by the Ozawa method, the Kissinger method, the Achar method and the Coats-Redfern method, respectively. The most probable kinetic functions of thermal decomposition for the first, the second and the fourth stages were suggested and their kinetic equations could be expressed as dα/dt=A/β·e^-E/RT(1-α), dα/dt=A/β·e^-E/RT(1-α)² and dα/dt=A/β·e^-E/RT(1-α)², respectively.
