• Top library match: 2,2,3,3-Tetrafluoropropan-1-ol #65316

• No bands characteristic of C–F stretching (1000–1400 cm⁻¹) are observed, making the top library hit (2,2,3,3‑tetrafluoropropan‑1‑ol) chemically unlikely.
• The expected strong ester carbonyl absorption near 1720 cm⁻¹, a key marker of conventional methacrylate polymers, is absent from the set of prominent peaks, challenging a simple methacrylate homopolymer identification.
• Without additional spectral data, the exact balance between aromatic, methacrylate, ether, and siloxane components remains undetermined.

Recommended next steps: Acquire the full FTIR spectrum over 4000–400 cm⁻¹, particularly the 1800–1650 cm⁻¹ (carbonyl) and 1400–600 cm⁻¹ (C–F, aromatic C–H, Si–O) regions, to confirm or rule out carbonyl, aromatic ring, and halogenated species. Compare the spectrum with reference spectra of known methacrylate polymers, fluorinated alcohols, and siloxane‑containing copolymers to resolve the ambiguity. If possible, perform complementary analysis (e.g., Raman spectroscopy, NMR, or XPS) to identify the presence of fluorine, silicon, or specific functional groups.
