β-Cyclodextrin(β-CD)-containing acrylic monomers were synthesized by using dicyclohexylcarbodiimide(DCC)as catalyst.Synthesis and characterization of using different reaction conditions,and the different mole cular structure with different substitution degree of β-CD-containing acrylic monomers were synthesized.Two kinds of β-CD-containing acrylic monomers,β-CD-3-A and β-CD-6-A carrying the same vinyl,were prepared reying on their reactivity of different hydroxyl groups in β-CD.Nuclear magnetic resonance(13C NMR)data indicated that,for β-CD-3-A,acylation occurs at C-2 and C-3 position of β-CD,and for β-CD-6-A,the acylation occurs at its C-2 and C-6 position,respectively.Moreover,the mono-[6-(2-acryloylaminoethyl)amino]-6-β-CD was obtained using acrylic acid as a raw material under the DCC catalyst.Its structure was confirmed by elemental analysis,1H NMR and IR.
