The crystallization of 3 polyamides 66 has been studied by optical microscopy and differential scanning calorimetry (DSC). Nonisothermal crystallization kinetics has been analyzed using Oza-wa's equation. Two polymers have close behaviors with a crystallization mainly spherulitic. The third one, which has the highest molar mass, is subject to intense transcrystallinity, which disturbs the crystallization kinetics (shoulder on the DSC curves and low Avrami exponent). For this polymer, original methods based on a detailed analysis of transcrystallinity have been applied to measure crystal growth rate and to determine the "intrinsic" crystallization kinetics, that is, not polluted by transcrystallinity
