摘　　要：用热台偏光显微镜观察羧酸盐类成核添加剂在聚对苯二甲酸乙二酯(PET)熔体中的行为,并用傅立叶变换红外光谱仪(FTIR)跟踪观察PET羧酸盐的形成。通过透射电镜和FTIR等仪器,对该聚合物金属离子盐的聚集进行了研究,初步阐明了化学成核机理。The behaviour of metal carboxylate nucleating additives in the melt of poly(ethylene terephthalate) (PET) was observed by hot-stage polarized light micro-scopy. The formation of PET metal ion salt was indicated by the study of Fouriortransfer infrared spectroscopy (FTIR). The aggregation of this polymer metalion salt was studied by means of transmission electron microscopy and FTIR. Themechanizm of chemical nucleation of PET were preliminary explained.
