以超支化聚酯为扩链剂，采用两步法合成了一系列新型超支化聚氨酯共聚物（HB-PUPCM）。采用差示扫描量热法（DSC）、动态力学热分析（DMA）、热重分析（TGA）、广角X射线衍射（WAXD）、偏光显微镜（POM）和双模式原子力显微镜（AFM）研究了HB-PUPCM薄膜的相变行为和形貌。HB-PUPCM是一种优良的高分子固-固相变储热材料。(c)\ 2006 Elsevier Ltd.保留所有权利。
A series of novel hyperbranched polyurethane copolymer (HB-PUPCM) using hyperbranched polyester as chain extender was prepared via a two-step process. The phase transition behaviors and morphology of the HB-PUPCM films were investigated using differential scanning calorimetry (DSC), dynamic mechanical thermal analysis (DMA), thermo-gravimetric analysis (TGA), wide-angle X-ray diffraction (WAXD), polarizing optical microscopy (POM) and tapping-mode atomic force microscopy (AFM). HB-PUPCM was proven to a good polymeric solid-solid phase change heat storage material. (c)\ 2006 Elsevier Ltd. All rights reserved.
