| 摘 要： | 研究了水滑石（HT）等四种结晶成核剂对聚对苯二甲酸乙二醇酯（PET）倩密度聚乙烯（PE-HD）共混物结晶性能和力学性能的影响。结果表明，加入HT，不仅可以提高PET／PlE—HD共混物中PET的结晶性能，而且还有助于改善共混物的力学性能；而添加离聚物（Surlyn 8920）或复合成核剂，PET结晶性能改善显著，但力学性能下降较多。

| Abstract: | The effect of nucleating agent on non-isothermal crystallization and mechanical properties of PET/PE-HD blends was investigated using DSC, SEM, and mechanical testing. The compound nucleating agents promoted non-isothermal crystallization of PET, however, the mechanical properties dropped obviously. HT may enhance both non-isothermal crystallization of PET and mechanical properties of the blends, specially the tougthness of the blends about 3 times higher than devoid one. |
