FTIR圖譜最符合含氧酯材料,很可能是聚合物或低聚物而非簡單烴類。最強的樣品證據是1708和1725 cm-1的羰基區域,以及1055、1098、1165、1178、1240和1285 cm-1的多個C-O伸縮譜帶,加上2935 cm-1的脂肪族C-H和3373 cm-1附近的寬O-H/N-H區域。譜庫頂部匹配為單羥基封端聚己內酯,而更廣泛的頂部候選圖譜主要由含氧酯聚合物如羥乙基甲基丙烯酸酯和聚酯型材料主導。然而,譜庫匹配品質非常弱,且沒有直接或相關的文獻證據獨立確認特定的命名聚合物。因此,最可支持的結論是更廣泛的含氧酯聚合物或低聚物方向,可能帶有羥基封端,而非嚴格歸屬於單羥基封端聚己內酯。
建議的下一步: Compare the full spectrum directly against authenticated FTIR references for Poly(caprolactone),monohydroxy terminated, poly(2-hydroxyethyl methacrylate), and common aliphatic polyesters such as poly(trimethylene succinate). Check for polyester-specific thermal behavior by DSC; a melting transition near the expected range for semicrystalline aliphatic polyester would help separate polycaprolactone-like material from methacrylate-based materials. Use 1H and 13C NMR to verify whether the sample contains caprolactone-type methylene environments, methacrylate backbone features, or mixed ester components. If the 3373 cm-1 band is important to the assignment, dry the sample and reacquire FTIR to determine whether the band persists as a true hydroxyl feature rather than adsorbed moisture.
