Abstract: The strength and stero-configuration of polyester film are analyzed by Infrared Spectroscopy theory based on the wave number displacement of characteristic absorption peak v^asc_c-o-c of the ester formed. Intern alrelations between anti-wear order law of hydroxyl fatty acids and vibration absorption peak v^asc_c-o-c of polyester formed by hydroxyl fatty acids is deduced by Quantum mechanics and classical mechanics, and the anti-wear order of hydroxyl fatty acids is reasonably explained, that is 13,14-dihydroxydoeosanoic acid >13(14)-monohydroxydocosanoic acid=9,10-dihydroxyoctadecanoic acid>9,10,12-trihydroxyoctadecanoic acid>9(10)-monohydroxyoctadecanoic acid. A net polyester film is formed by 13,14-dihydroxydocosanoic acid and a linear polyester film is formed by 9,(10)-monohydroxyoctadecanoic acid and 13(14)-monolydroxydocosanoic acid.
Keywords: hydroxyl vegetable oil fatty acid, anti-wear rule, infrared spectroscopy, quantum mechanics, classical mechanics.
