N2 - Non-isothermal crystallization kinetics and subsequent melting behavior for three kinds of ethylene-acrylic acid copolymer (EAA) are investigated via differential scanning calorimetry (DSC). From the Jeziorny method, the crystallization rate of the primary stage is significantly influenced by the competitive mobility of chains. While the crystallization rate in the secondary stage decreases in order of acrylic acid (AA) content in copolymers. Mo's method can also provide a good fitting. Difference between the Jeziorny method and Mo's method analysis is because of a higher effect of non-crystallizable chain ends. The effective activation energy is also determined via Kissinger's method.
