用TMA（静态热机械分析法）、DSC（差效扫描式量效法）等分析方法研究了壳聚糖和聚乙二醇共混物的相变行为。当共混物中亮聚糖组分含量高于15％、温度高于聚乙二醇熔点时，共混物中的聚乙二醇不融化成液体，仍保持为固体，共混物表现出固态相变行为。TG－DTA（联合热重量-差示热分析法）分析表明该共混物具有较好的效稳定性。
The phase transition behavior of chitosan and polyethylene glycol blends was studied by TMA (static thermomechanical analysis) and differential scanning calorimetry (DSC). When the content of the bright polysaccharide in the blend is higher than 15% and the temperature is higher than the melting point of the polyethylene glycol, the polyethylene glycol in the blend does not melt into a liquid and remains as a solid, and the blend shows Solid phase transition behavior. TG-DTA (combined thermogravimetric-differential thermal analysis) analysis showed that the blend has good stability.
