高分子化合物如何分析其结构？

详细的了解该化合物的结构几乎不可能。一般分析高分子化合物的结构采用气相色谱法，但也只能初步了解是由什么组成，并不能分析结构。

There is no single diagnostic method for this purpose.
However, one can use FT-IR to verify if polymer formulations are correctly blended, use DSC to check for contamination, use a capillary rheometer to determine the melt viscosity. By use of a combination of other analytical techniques eg. GC-MS, HPLC, XRF and TGA, it is possible to obtain detailed knowledge of polymer composition. Molecular weight distributions can be determined using GPC techniques. Chemical structural information can also be gained using a variety of NMR techniques.

(Don't forget to use some hand-wave stuffs.)

使用红外或是核磁共振等方法也只能检测出该高分子物质里含有什么官能团,也不能完全的反映出他具体的分子结构

无法达到要求。
