Because of the current interest in sustainability, environmental stewardship, and green chemistry, there has been a lot of interest in using agro-based raw materials for the design of polymeric materials. One of the promising biorenewable materials is sucrose, which is inexpensive and widely available. In this work we have carried out the synthesis of sucrose–toluene diisocyanate-based polyurethane through microwave-assisted reactions. Comparisons of conventional heat versus microwave reactions have been made. Microwave-assisted synthesis has been found to significantly decrease the reaction time and save energy relative to conventional heat. The sucrose polyurethane has turned out to be a suitable matrix to prepare semi-interpenetrating polymer networks (semi-IPNs) involving a second material. Two examples shown in this work are the semi-IPNs of sucrose polyurethane with polycaprolactone and soybean oil. Characterization of the polymers has been conducted with ¹³C NMR, FT-IR, size-exclusion chromatography, and thermal analysis.

微波辅助合成聚己内酯和豆油的蔗糖聚氨酯及其半互穿聚合物网络

由于当前对可持续性，环境管理和绿色化学的关注，人们对使用农业基原材料进行聚合物材料设计产生了浓厚兴趣。蔗糖是一种有前途的生物可再生材料，它便宜且可广泛获得。在这项工作中，我们通过微波辅助反应进行了蔗糖-甲苯二异氰酸酯基聚氨酯的合成。进行了常规热反应与微波反应的比较。已经发现，微波辅助合成相对于常规热显着减少了反应时间并节省了能量。事实证明，蔗糖聚氨酯是制备涉及第二种材料的半互穿聚合物网络（semi-IPN）的合适基质。这项工作显示的两个例子是蔗糖聚氨酯与聚己内酯和大豆油的半IPN。聚合物的表征已通过¹³ C NMR，FT-IR，尺寸排阻色谱法和热分析。
