【摘要】 用苯酐和新戊二醇为原料制备了热塑性聚氨酯用聚酯多元醇,重点讨论了在实验室制备过程中,醇酸比、酯化反应温度、真空度和酯化时间对聚酯树脂合成的影响;对该聚酯树脂分别用红外光谱和核磁共振氢谱进行结构表征,并从理论上讨论了其耐水解稳定性。更多还原

【Abstract】 This paper has introduced a method that benzoic anhydride polyester polyol used to thermoplastic polyurethane was synthesized in lab with benzoic anhydride and neopentyl glycol,focused on the discussion of the influence of ration of alcohol to acid.esterification temperature,vacuum,esterification time on the synthesis of polyester resin.The molecular structure of the polyester resin was characterized by IR and ’H-NMR spectroscopy,and its stability in the water was discussed theoretically.更多还原
