摘　　要：利用红外吸收光谱及核磁共振波谱仪的一维和二维技术对一种未知聚合物试样进行鉴定。由核磁共振二维技术分析得出聚醚酯的序列结构及其分布。结果表明:该未知聚合物试样为聚醚酯弹性体,由对苯二甲酸、间苯二甲酸、新戊二醇、乙二醇、聚四氢呋喃醚共聚而成。An unknown polymer was determined by one-dimension and two-dimension technologies of infrared absorption spectroscopy and nuclear magnetic resonance. The sequence structure and distribution of polyether-ester were analyzed by two-dimension technology of nuclear magnetic resonnance spectroscopy. The results showed that the unknown polymer was identified as a polyether-ester elastomer which was prepared from terephthalie acid, isophthalic acid, neopentyl glycol, ethylene glycol and polytetrahydrofuran glycol via copolymerization.
