Identification Result

The sample is identified as Copolymerized PP, a polypropylene copolymer. The observed infrared spectrum matches the library reference spectrum of Copolymerized PP (#713) with high similarity (0.875), and the overall band pattern is characteristic of polyolefin materials containing both methyl and methylene groups 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.

Detailed interpretation

  • Top library match: Copolymerized PP #713
  • Direct‑literature evidence returned a wide range of group assignments (e.g., O–Mg–O, Zn–O, tetrahedral sites, Si–O) from sources that are not chemically compatible with the polyolefin material; these reflect the diversity of the literature corpus rather than meaningful spectral evidence for the present sample.
  • The small peak at about 1033 cm⁻¹ could partly reflect minor oxidation or the presence of additives, but it does not undermine the primary identification.
  • The exact comonomer composition (e.g., ethylene content) cannot be inferred from the FTIR spectrum alone without a suitable calibration.

Recommended next steps: Perform differential scanning calorimetry (DSC) to confirm the copolymer type (random or block) and to estimate the ethylene/propylene ratio. If further confirmation is required, obtain a ¹³C NMR spectrum to quantify the levels of ethylene incorporation.
