New Amphiphilic Glycopolymers Based on a Polycaprolactone‐maleic anhydride Copolymer Backbone: Characterization by 15N NMR and Application to Colloidal Stabilization of Nanoparticles

Abstract

Abstract8‐Amino‐3,6‐dioxaoctyl α‐D‐mannopyranoside and 8‐amino‐3,6‐dioxaoctyl β‐D‐galactopyranoside were prepared for coupling with a copolymer made from PCL macromonomers and MA. The new glycosyl compounds as well as PCL macromonomers were synthesized by appropriate techniques and fully characterized. The grafting of the latter with the functionalized copolymer was ascertained by 15N NMR experiments. The glycopolymers thus obtained were used in conjunction with Pluronic® F‐68 for the stabilization of PCL nanoparticles prepared by the emulsification‐diffusion technique. The stabilization of these nanoparticles upon storage and after centrifugation was investigated as well.magnified image
