Abstract/OtherAbstract:
pH- and thermo-sensitive (1→4)-2-amino-2-deoxy-β-d-glucan (i.e. chitosan) graft copolymer was prepared by reversible addition fragmentation chain transfer polymerizations of N-isopropylacrylamide with 4-methylbenzenesulfonic acid (i.e. tosylic acid)-chitosan complex. The polymerization was controlled well, and the amino group of chitosan could be deprotected easily and mildly with 15% Tris solution. The model aldehyde vanillin was conjugated with amino group of Chitosan-g-PNIPAM via Schiff base bond (Loading efficiency, LE=77.6mg/g), and the drug release could be controlled with temperature and pH. This property may promote the chitosan graft copolymer to be used in the field of "smart" drug delivery.
