The effect of self-seeding nucleation on the crystallization behavior of paly(trimethylene terephthalate) (PTT) was studied.The result of differential scanning calorimetry(DSC)indicated that the crystallization temperature of PTT increased obviously under the influence of self-seeding nucleation.Avrami equation was applied to analyze the isothermal crystallization process of PTI.The average value of Avrami exponent is n=3.34
suggesting that the primary crystallization may correspond to a three—dimensional spherulitic growth.Self-seeding nucleation leads to the decrease of crystallization active energy and chain folding work
promotes the overall crystallization process of PTT.
