Abstract
AbstractRAFT homopolymerization of 2‐(diisopropylamino)ethyl methacrylate (DPA) and 2‐(diethylamino)ethyl methacrylate (DEA) and their random copolymerization were investigated. The random copolymers of DPA‐ran‐DEA were synthesized and used as macro‐CTA to prepare poly(DPA‐ran‐DEA)‐b‐poly(N‐(2‐hydroxypropyl) methacrylamide) amphiphilic block copolymers. The 1H NMR and GPC measurements confirmed the successful synthesis of these copolymers. The potentiometric titration results showed that the pKb values of these copolymers were in the range of 6.7 ∼ 7.7 and linearly varied with the DPA/DEA composition, regardless of the block length of HPMA. The pH‐induced micellization in PBS solution was verified by fluorescence spectroscopy. The dynamic light scattering evaluation showed that the hydrodynamic diameters of these micelles are between 37 ∼ 43 nm © 2008 Wiley Periodicals, Inc.
