. The non-isothermal kinetic parameters were obtained via the analysis of the thermogravimetric and differential thermogravimetric (TG-DTG) curves by using Flynn-Wall-Ozawa method and Kissinger method. The thermal decomposition mechanism of abietic acid was studied with four integral methods (Šatava-Šesták
MacCallum-Tanner
ordinary integral and Agrawal). The results show that the thermal decomposition mechanism is nucleation and growth
and the mechanism function is Avrami-Erofeev equation with n equates 1/2. The activation energy and the pre-exponential factor are 64.04 kJ·mol
