Discrimination of Different Polyamides by IR

For the different polyamides had different structure and property,the types of polyamide would be discriminated for production.The different polyamides were discriminated by infrared spectra(IR),including the sample preparation,IR analysis,conclusion and suggestion.The IR analysis outlined the same characteristic of different polyamides,and analyzed the difference of polyamides for nylon6/nylon66,nylon11/nylon12,nylon610/nylon612/nylon 1010,nylon6T/nylon9T,respectively.
