A series of PBIEM-PB-PEGMA molecular brushes was synthesized by ATRP (Atom Transfer Radical Polymerization) of 4-Vinylphenylboronic acid and Di(ethylene glycol) methyl ether methacrylate using PBIEM-Br macroinitiator as an initiator. These brushes can be crosslinked intramolecularly by the addition of the crosslinker and recovered to the original state by the change of pH. This process can be reversibly controlled by pH. We characterized the reversible crosslinking behavior by 1H NMR, GPC, AFM, and SAXS. |
