Abstract： The polyethylene glycol molecular structure had been studied by middle infrared (MIR) spectroscopy. The infrared absorption mode of polyethylene glycol molecular included ν■, ν■, ν■, δ■, ω■, ρ■ and ν■. Temperature-dependent middle infrared (TD-MIR) spectroscopy of polyethylene glycol molecular were researched also. In the temperature range from 303 K to 473 K, the infrared absorption frequency and intensity of polyethylene glycol molecular changed obviously and the thermal denaturation mechanisation were discovered also. The paper demonstrated the key roles of MIR and TD-MIR spectroscopy in the analysis of structure and thermal denaturation of the important ceramic industry additives (polyethylene glycol).
