Abstract

Poly(N‐tert‐butylaziridine) (polyTBA) macromonomers with allylamino‐, allyloxy‐ and methacrylate end‐groups were synthesized via deactivation of living polyTBA with appropriate nucleophiles. The macromonomers were copolymerized with N‐vinyl‐2‐pyrrolidone (NVP), 2‐hydroxyethyl methacrylate (HEMA) and isoprene (Is). Two types of graft copolymers were obtained: the first one is constituted of hydrophilic backbone (polyNVP or polyHEMA) and hydrophobic uniform polyTBA side chains. The second type is composed of a flexible hydrophobic polyIs backbone and hard hydrophobic polyTBA side chains which, however, become water swellable after quaternization.
