摘　　要：The effects of self-seeding nucleation on the crystallization behavior and properties of poly(trimethylene terephthalate) were studied.Differential scanning calorimetry(DSC) results indicated that the crystallization temperature of poly(trimethylene terephthalate) increased obviously(increased about 20℃) after the process of self-seeding nucleation.The results of polarized light microscopy(PLM) showed that the spherulite size decreased markedly from 40 μm to 8 μm.The effects of self-seeding nucleation on the crystallization behavior and properties of poly(trimethylene terephthalate) were studied.
