| 摘 要： | 利用差示扫描量热仪对不同配比的聚萘二甲酸乙二醇酯/聚对苯二甲酸丙二醇酯(PEN/PTT)共混体系的熔融行为进行了分析,发现在共混体系中两组分形成各自的晶体,PEN和PTT的熔点均随另一组分含量的增加而下降。根据Nishi-Wang方程,按300℃计算,由PEN/PTT共混体系中PEN熔点下降计算所得到的相互作用能密度为-0．214 2 J/cm~3,相互作用参数为-0．006 8,表明PEN/PTY共混体系在熔融态是热力学性质稳定的相容体系。

| Abstract: | The melting behavior of polyethylene-2,6-naphthalate/polytrimethylene terephthalate(PEN/PTF)blends at different ratios was studied with a differential scanning calorimeter.It was found that the two polymers in the blend system formed the crys- tals individually.The melting point of PEN or PTT was decreased while increasing the content of one another component.Accord- ing to Nishi-Wang equation,the interaction energy density and interaction parameter of PEN/PTT blend system at 300℃were calculated as-0. 214 2 J/cm~3 and-0.006 8 respectively during the drop of PEN melting point,which indicated that the PEN/ PTF blend system was a thermodynamics stable compatible system at the melting state. |
