光譜最符合含羰基的酯類材料,譜庫將聚(丙烯酸乙酯)列為最接近的命名候選物。然而,整體匹配強度非常弱,並且沒有直接參考或相關文獻支持來證明確定的材料歸屬。觀察到的譜帶支持廣泛的含酯有機組成,可能屬於丙烯酸酯或聚酯類方向,但現有證據不足以具體確認聚(丙烯酸乙酯)。
建議的下一步: Recollect or inspect the full FTIR spectrum, especially the 1500-600 cm⁻¹ fingerprint region, to verify ester C-O-C band patterning and look for polymer-specific backbone features. Compare the sample directly against authenticated spectra of Poly(ethyl acrylate), a generic acrylic polymer, and representative aliphatic polyesters such as poly(butylene adipate). If the sample is a coating, adhesive, or extractable residue, run complementary analysis such as ATR-FTIR repeat measurement, DSC, or Py-GC/MS to distinguish an acrylate polymer from a polyester or small-molecule ester. Check for repeatable carbonyl peak shape and position across replicate measurements, since ester subclass assignment often depends on the detailed carbonyl and C-O band profile.
