摘    要:系统地研究了四种成核剂:N-A、液晶VectraA950、滑石粉(Talc)、乙撑双硬脂酰胺(EBS)对聚对苯二甲酸乙二醇酯(PET)的结晶行为的影响。采用差式扫描量热仪(DSC)研究了PET/成核剂复合体系的非等温结晶行为,通过小角激光散射(Sals)、X衍射(XRD)对PET/成核剂复合体系的晶体尺寸和晶体结构进行了研究。结果表明,引入成核剂后,PET的结晶行为有较大改善,结晶峰向高温方向移动,且变尖锐,结晶尺寸变小,结晶度提高,除EBS外,均使PET结晶诱导时间减少。在这四种成核剂中,离子聚合物成核剂N-A成核效果最好。

关 键 词:聚对苯二甲酸乙二醇酯  成核剂  结晶行为  晶体结构

Abstract:In this paper, the effects of four kinds of nucleating agents: N-A, LCD VectraA950, talc and EBS, on the crystallization behavior were systematic studied. The non-isothermal crystallization behaviors of PET/nucleating agent blends by Differential Scanning Calorimetry (DSC), the crystal size and crystallization structure of PET/nucleating agent composites were investigated by Small Angle Laser Scattering (Sals) and X Ray Diffraction (XRD), respectively. The study indicated that added with nucleation agents, ...
Keywords:ethylene bis-stearamide  nucleating agent  crystallization behavior  crystal structure
