【摘要】 <正> 近年来,微波辐射合成高吸水性树脂由于在工艺上的简便性、环保性以及产品性能上的优势已成为高吸水性树脂合成的重要发展方向,但是对于微波条件下所合成树脂的结构与性能之间关系的研究较少。本实验在微波辐射条件下合成了淀粉、丙烯酸、AMPS三元共聚高吸水性树脂,并采用FT-IR、13C CP/MAS NMR以及扫描电镜等方法对淀粉、AMPS均聚物和纯化的三元接枝共聚物的更多还原

【Abstract】 A super absorbent of starch, 2-acrylamido-2-methyl-propanosulfonic acid (AMPS) and sodium acrylate was synthesized by microwave irradiation. The structure of polymer was characterized by FTIR, 13C CP/MAS NMR and SEM, and the morphology of surface of sample was studied. The results showed that the morphology of polymer was changed to some extent under microwave irradiation, and the swelling rate of polymer synthesized by microwave polymerization was faster than that synthesized by traditional method.更多还原
