采用差示扫描量热法（DSC）和动态力学分析法（DMA）研究了不同质量比的硝化棉／聚乙二醇（NC／PEG）共混体系的相容性。结果表明，NC／PEG共混体系中PEG 的熔点、结晶度和结晶熵随 NC 含量的增加明显降低，共混组分相互作用参数χ1，2为负值，即共混体系在热力学上具有相容性。共混体系的玻璃化转变温度随 NC 含量的增加均向低温移动，并且当共混体系中NC与PEG质量比为1∶1时，共混体系呈现单一的玻璃化转变温度。

The compatibility of nitrocellulose/polyethylene glycol (NC/PEG)blended system with different mass ratio was studied by DSC and DMA.Results show that with increasing the content of NC in NC/PEG blended system,the melting point,crystallinity and entropy of crystallization of PEG decrease obviously.The value of interaction parameterχ1,2 of the blended component is negative,i.e.the blended system possesses the compatibility on thermodynamics.With increasing the content of NC,the glass transition temperature of the blended system shifts downwards.When the mass ratio of NC and PEG in the blended system is 1∶1 ,the blended system reveals a single glass transition temperature.
