SYNTHESIS OF AMPHIPHILIC GRAFT-COPOLYMERS BY RING-OPENING POLYMERIZATION OF 2-METHYL-2-OXAZOLINE INITIATED BY POLY[ISOBUTENE-CO-(P,M-CHLOROMETHYLSTYRENE)] MACROINITIATORS

romethylstyrene)]-graft-poly(2-methyl-2-oxazoline) graft copolymers (G P) were prepared by the ''grafting from'' method through the cationic polymerization of 2-methyl-2-oxazoline (MeOXA) initiated by a statisti cal copolymer is isobutene and chloromethylstyrene. The unusual viscos ity behavior in chloroform solution of these polymers, the dynamic las er light scattering analysis in aqueous solution, as well as the solub ility in polar solvents Like water and methanol demonstrate the amphip hilic character of the graft copolymers and indicate the formation of aggregates in solution.
