新型聚氨酯酰亚胺的合成及其性能
Synthesis and property study of a new polyurethane-imide
摘要
Abstract
A kind of glycol containing imide function was synthesized from trimellitic anhydride,4,4＇-diaminodiphenyl ether and diethylene glycol.A new type of polyurethane-imide elastic material was synthesized from isocyanate terminated PU prepolymer,glycol containing imide function.The productions are characterized with Fourier transform infrared spectroscopy（FT-IR）,differential scanning calorimetry（DSC）and thermal gravimetric analysis（TGA）.TGA results show that the thermal property of the samples is obviously improved compared to PU.Td has an increase of 12%,T50% has an increase of 45 ℃,and the weight of remained polymer has an increase of 18%.The glass transition temperature（Tg）is found in both obtained PUIs block copolymers,and two steps weight loss in an N2 atmosphere is observed.The PUIs are soluble in strong polar solvents,and also show certain resistance against dilute inorganic acid corrosion.关键词
