Aromatic, oxygenated polymer with ester/carboxylic acid and amine/hydroxyl groups
Sample & Measurement Parameters
Identification Result
75%The FTIR spectrum indicates an aromatic, oxygenated polymer exhibiting strong ester/carboxylic acid carbonyl near 1734 cm-1, C-O-C ether stretching at 1096 cm-1, aromatic ring vibrations at 1557 and out-of-plane bending at 669, 730, 802 cm-1, aliphatic C-H stretches in the 2846–2978 cm-1 region, and a broad O-H/N-H envelope centered around 3397 cm-1. While the spectral library best matches Poly(methyl vinyl ether:maleic acid), the clear aromatic absorption pattern suggests a more complex aromatic-containing structure FTIR In-Depth Interpretation was not selected for this task, so this section shows the library-search result only and no deep AI interpretation was run.
