摘　　要： 通过S-(-)-α-苯乙胺与甲基丙烯酰氯的缩合反应,合成出可聚合酰胺类手性功能单体S-(-)-N-α-苯乙基-甲基丙烯酰胺(SPA),并在四氢呋喃溶剂中与功能单体异丙基丙烯酰胺(NIPAM)共聚制备得到手性微凝胶。FTIR和NMR研究结果表明手性单体和手性微凝胶成功合成。SEM结果表明手性微凝胶胶粒尺寸为280～400nm,但单分散性差。浊度和DSC结果表明手性单体的引入降低了PNIPAM微凝胶的温敏性。 The acrylamide polymerizable chiral functional monomer (s)-(-)-N-α-Phenylethyl- methacrylamide (SPA) was synthesized using condensation between (s)-(-)-N-α-Phenylethyl and methacryloyl chloride.The chiral microgel was prepared by copolymerizing SPA and function monomer N-isopropylacrylamide (NIPAM) in tetrahydrofuran solvent.The results from FTIR and NMR show that chiral functional monomer (SPA) and chiral microgel were synthesized successfully.The result from SEM shows that the particle size of chiral microgel ranged from 280nm to 400nm with poor monodispersity.The results from turbidity and DSC show that the temperature-sensitivity of chiral microgel was decreased with increasing chiral monomer content.
