Facile Preparation of Nanogels Using Activated Ester Containing Polymers.

A facile methodology to prepare water-dispersible nanogels based on pentafluorophenyl acrylate and polyethylene glycol methacrylate random copolymer and diamine cross-linkers has been developed. Cross-linking reaction was characterized by FTIR and 19F NMR. We show that those nanogels : (i) are water-dispersible; (ii) can conveniently encapsulate lipophilic guest molecules; (iii) can be prepared with different nanosizes; (iv) are engineered to allow for surface decoration with additional functional groups.
