Isothermal crystallization studies on nylon 6.6 and 6.10 by calorimetry

The DSC technique was used to investigate the isothermal crystallization of nylon 6.6 and nylon 6.10. It is shown that the Avrami equation in the case of the crystalline polymers is useful during the hole crystallization process. The observed differences in the activation energies of crystallization of annealed and untreated nylon 6.6 and 6.10 polymers are due to the differences in inner order in the specimen during the primary and the secondary crystallization.
