Summary
Group-transfer polymerization of benzyl methacrylate has been shown to proceed smoothly to give polymers of low (Mw/Mn < 1.1) polydispersity, with good control of molecular weight. Removal of the benzyl groups can be achieved easily via catalytic hydrogenation at room temperature and takes place without main chain scission. This is thus a very effective route for the synthesis of monodisperse poly(methacrylic acid)s.
