Sucrose-1,6-hexamethylene diisocyanate (HDI) cooligomers were synthesized and used as new polyols for poly(ε-caprolactone) (PCL)-based polyurethanes. The polyaddition reaction of sucrose and HDI was monitored by MALDI-TOF MS. It was found that by selecting appropriate reaction conditions, mostly linear oligomer chains containing 16 sucrose units could be obtained. For the synthesis of polyurethane networks, prepolymers were prepared by the reaction of poly(ε-caprolactone) (PCL, 10 kg/mol) with HDI or 4,4'-methylene diphenyl diisocyanate (MDI) and were reacted with sucrose-HDI cooligomers. The so-obtained sucrose-containing polyurethanes were characterized by means of attenuated total reflectance Fourier-transform infrared spectroscopy (ATR-FT IR), swelling, mechanical (uniaxial tensile tests) and differential scanning calorimetry (DSC).
蔗糖-1,6-己二异氰酸酯（HDI）三聚体被合成并用作新型多元醇用于聚（ε-己内酯）（PCL）基聚氨酯。蔗糖和 HDI 的加聚反应通过 MALDI-TOF MS 进行监测。结果发现，通过选择适当的反应条件，可以得到主要含有 16 个蔗糖单元的线性寡聚物链。为了合成聚氨酯网络，将聚（ε-己内酯）（PCL，10 kg/mol）与 HDI 或 4,4'-亚甲基二苯基二异氰酸酯（MDI）反应制备预聚物，然后与蔗糖-HDI 三聚体反应。通过衰减全反射傅里叶变换红外光谱（ATR-FTIR）、溶胀、机械（单轴拉伸试验）和差示扫描量热法（DSC）对所得含蔗糖的聚氨酯进行了表征。
