SYNTHESIS OF POLY((N-TERT-BUTYLAZIRIDINE) MACROMONOMERS AND GRAFT-COPOLYMERS WITH UNIFORM SIDE-CHAINS)

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