Abstract: The non-isothermal crystallization behavior of PA6/PPO blends was studied with differential scanning calorimetry. The methods of Jeziorny and Mo were used to analyze the non-isothermal crystallization kinetics of the blends. Results demonstrated that the crystallization of PA6 could be accelerated by PPO，however，depressed by PPO-g-MAH, SEBS-g-MAH and SEBS. Both Jeziorny and Mo methods were suitable for the analysis of non-isothermal crystallization of PA6/PPO blends.
