Abstract In recent years, phosphaphenanthrene-based flame retardants have been extensively studied due to their good compatibility and flame retardancy. In this work, PLA/MAH-DOPS flame retardant composites were prepared by adding maleic anhydride-9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-sulfide (MAH-DOPS) as flame retardant into polylactic acid (PLA), then the thermal degradation process was studied by TG/DTG method, finally the thermal degradation kinetic parameters, including the activation energy (E) and pre-exponential factor (A), the thermal degradation kinetic mechanism function and reaction order were calculated by Kissinger method, Flynn-Wall-Ozawa method and Coats-Redfern method. The results indicate that compared with pure PLA, the initial decomposition temperature(T_5%), maximum thermal weight loss rate (R_max) and peak temperature (T_P) of PLA/MAH-DOPS are all decreased, while the carbon residue rate is increased. The thermal degradation kinetic parameters are E_K(PLA)=174.02 kJ/mol, E_O(PLA)=178.45 kJ/mol, lnA_K(PLA)=31.90, E_K(PLA/MAH-DOPS) =124.93 kJ/mol, E_O(PLA/MAH-DOPS)=126.37 kJ/mol and lnA_K(PLA/MAH-DOPS)=24.43. The mechanism functions of the thermal degradation of PLA and PLA/MAH-DOPS are both g(α)=[-ln(1-α)]^3/4, with the reaction order n=3/4, and the thermal degradation mechanism is random nucleation and its subsequent growth.
