高分子化合物如何分析其結構?

詳細的了解該化合物的結構幾乎不可能。一般分析高分子化合物的結構采用氣相色譜法,但也只能初步了解是由什么組成,并不能分析結構。
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.)
