| 摘 要： | 研究了新型复合成核剂水滑石(HT)／离聚物(Surlyn8920)／聚乙二醇(PEG)对不同特性粘数聚对苯二甲酸乙二醇酯(PET)非等温结晶性能的影响。通过差示扫描量热仪测试了PET的结晶峰温度T_(mc)和熔融峰温度(T_m)。结果表明,复合成核剂各组分及PET的质量比为0.5:3.0:3.0:100.0时,各种PET的过冷度(T_m-T_(mc))均显著减少．半结晶时间(1gt_(1／2))也明显降低。而且,复合成核剂对不同特性粘数PET结晶性能的改善是一致的。

| Abstract: | The effect of the nucleating agent Hydrotalcite(HT)/ionomer(Surlyn8920)/ poly(ethylene glycol)(PEG)on the non-isothermal crystallization behaviors of Poly(ethylene terephthalate)(PET)with different inherent viscosities was investigated.The measurements of crystallization temperature(T_(mc)) of cooling crystallization peak of PET in a non-isother- mal cooling process and melt temperature(T_m)of melt peak of PET were measured through differential scanning calorimetry(DSC)analysis.The results show that the degree of super- cooling(T_m-T_(mc)) and the halftime(lgt_(1/2))in crystallization decreases when mass ratio of the nucleating agent(HT/Surlyn/PEG)and PET is 0.5:3.0:3.0:100.0.The effects on non-isothermal crystallization modification of PET with different inherent viscosities are con- formably. |
