Explanation / Answer

Interpretation of IR spectrum:

1) Aband at 3298 cm-1 indicates the presence of NH Stretching

3)Aband at 2931 cm-1 indicates the presence of C-H Stretching

4)A band at 2158 cm-1 indicates the presence of Carbon--Carbon triple bond Stretching or overtone band

5)Aband at 1682 cm-1 indicates the presence of amide C=O Stretching

6)Aband at 1632 cm-1 indicates the presence of amide C=C Stretching

The polymer may be polyamide type
