Ring‐opening polymerization of 2‐methyl‐2‐oxazoline initiated by 2‐( p ‐nitrobenzenesulfonato)ethyl methacrylate follows the so‐called “living mechanism”, i.e. fast initiation compared to slow propagation and no chain transfer. Accordingly, methacryl macromonomers having homopolymers, block or random copolymers of 2‐methyl and 2‐pentyl‐2‐oxazoline backbones with narrow molecular weight distribution were obtained. Termination of the propagating species by ion‐exchange or aminolysis with triethylamine yielded hydroxyl and quaternary ammonium terminated macromonomers, respectively.
