摘要
Semi-aromatic copolyamides PA10T10I and PA10T10F based on bio-based poly(decamethylene terephthalamide) (PA10T) were synthesized by a two-step polycondensation technique. The nonisothermal crystallization of these semi-aromatic polyamides was investigated by differential scanning calorimetry. Avrami theory modified by Jeziorny and Mo equation was used to describe the nonisothermal crystallization kinetics of these semi-aromatic polyamides, respectively. The crystallization activation energies were obtained by Kissinger method. The crystallization temperature, crystallization rate and activation energy were explained by regularity and flexibility of chain.
