Surface-initiated ATRP of 2-(methacryloyloxy)ethyl 2-(trimethylammonio)ethyl phosphate on Phynox

► 11-(2-Bromoisobutyrate)-undecyl-1-phosphonic acid has been synthesized. ► 11-(2-Bromoisobutyrate)-undecyl-1-phosphonic forms a monolayer on Phynox substrate. ► This monolayer plays the role of the initiator for MPC ATRP polymerization. ► Two conditions have been used: unheated during 24 h and heated at 90 °C during 1 h. ► Heating the system led to a more hydrophilic polymer.
