| Abstract: | Novel water-soluble amphiphilic ternary graft copolymers(COS-g-PCL-b-MPEG) were synthesized by N,N’-dicyclohexyl carbodiimide(DCC) coupling reaction between chitooligosaccharide(COS) with MPEG-b-PCL-COOH, which was synthesized via ring-opening polymerization of ε-caprolactone(CL) with methoxy poly(ethylene glycol)(MPEG) as an initiator and subsequent carboxylation by succinic anhydride. The che-mical composition of the graft copolymers was studied by 1H NMR spectrum. In aqueous solutions, stable supramolecular hydrogels could be rapidly fabricated via the inclusion compound between the MPEG-b-PCL graft of COS derivates and α-CD. The supramolecular structure of the hydrogels was revealed by WXRD analysis. The temperature sweep test results show that no gel-sol transition temperature appears over the range from 20 ℃ to 60 ℃ for the obtained hydrogels. |
