poly[isobutene‐ co ‐( p , m ‐chloromethylstyrene)]‐ graft ‐poly(2‐methyl‐2‐oxazoline) graft copolymers ( GP ) were prepared by the “grafting from” method throught the cationic polymerization of 2‐methyl‐2‐oxazoline (MeOXA) initiated by a statistical copolymer is isobutene and chloromethylstyrene. The unusual viscosity behavior in chloroform solution of these polymers, the dynamic laser light scattering analysis in aqueous solution, as well as the solubility in polar solvents like water and methanol demonstrate the amphiphilic character of the graft copolymers and indicate the formation of aggregates in solution.
