The cobalt-mediated radical polymerization of N-vinyl-3-ethyl imidazolium bromide (VEtImBr) is first carried out until high conversion in water at 30 degrees C
using an alkyl bis(acetylacetonate) cobalt(III) adduct as initiator and controlling agent. The as-obtained hydrophilic poly(N-vinyl-3ethyl imidazolium bromide) (PVEtImBr) is then used as a macroinitiator for the CMR-PISA of N-vinyl-3-octyl imidazolium bromide (VOcImBr). Self-assembly of the amphiphilic PVEtImBr-b-PVOcImBr block copolymer
i.e.
of PIL-b-PIL-type
rapidly takes place in water
forming polymer nanoparticles consisting of a hydrophilic PVEtImBr corona and a hydrophobic PVOcImBr core. Preliminary investigation into the effect of the size of the hydrophobic block on the dimension of the nanoparticles is also described. Keywords Author Keywords:block copolymers
