淀粉与木糖醇共混物的性能于九皋，郑华武（天津大学化学系天津３０００７２）关键词淀粉，木糖醇，共混，热塑性研究具有环境条件下可降解的塑料已成为国内外专家学者广泛关注的研究课题。淀粉具有类似高聚物的分子结构，但由于分子量大，分子之间的亲合力强，很难加工成...
The starch/xylitol blends were extruded in a single extruder.Their properties such as mechanical properties,rheological properties,as well as the effect of components and processing parameters,including the processing time and temperature,on these properties were studied.The activation energy for viscous flow was about 225.1 kJ/mol.The micromophology and crystallinity of the blends have been investigated by scanning electronic microscope and X-ray diffraction method.The result of tests showed that the starch granules were broken and the crystallinity decreased in the blends of starch and xylitol.
