摘要
用密度梯度管法、红外光谱法和x射线衍射分峰法,测定聚萘酯(PEN—2.6)的结晶度,并对3种方法测定的结果进行了比较.
The degree of crystallinity of poly (ethylene-2.6naphthalate) has been measured by density gradient column, infrared method and computational multipeak resolution method for x-ray diffraction and the results of the three methods have been Compared.
