用热分析、动态粘弹谱、红外光谱和小角X光散射的实验结果,证实了在聚对苯二甲酸丁二酯-聚己内酰胺嵌段共聚物(简称PBT-PA_6)的无定形区中,两嵌段间具有良好的相容性,两嵌段间有氢键生成。
The experimental results of thermal analysis, dynamic viscoelastic spectroscopy, infrared spectroscopy and small-angle X-ray scattering confirm that in the amorphous region of polybutylene terephthalate-polycaprolactam block copolymer (PBT-PA_6) Two blocks have good compatibility between the two block hydrogen bonds generated.
