| 摘 要： | 经缩聚和加聚反应分步聚合制得聚氨酯大孔吸附树脂,通过红外光谱分析等手段证实大孔树脂的骨架结构与原设计一致,在于态下测得的比表面积为120m2/g,且性能稳定、孔径分布窄、机械强度高。利用DSC、SAXS对其骨架结构进行研究的结果表明:聚氨酯大孔树脂具有微相分离的形态结构,且存在两种分散相。

| Abstract: | The polyurethane macroporous segmented copolymers were synthesized by two step polymerization. The products were investigated by FTIR, DSC and SAXS techniques .The results show that the structure of macroporous adsorbents is as expected. As the specific surface area and pore diameter data are concerned, they have comparable physical properties to commercial porous polymers.The morphology of polyurethane macroporous copolymer is three domain structures, which would be beneficial to the adsorption behavior and selectivity of adsorbents. |
