| Abstract: | This paper introduced a method that prepared polyester polyols used in the thermoplastic polyurethane with the material of benzoic anhydride and neopentyl glycol.Focused to discuss on the influence in the ratio of alcohol to acid,esterified reactive temperature,degree of vacuum and esterified time for which polyester resin was synthesized in the laboratory.The molecular structure of the polyester resin was characterized by IR and ~1H-NMR spectrometer separately,and its stability was discussed in water theoretically. |
