Abstract

-isoprene (I) or butadiene (B)) prepolymers (bearing hydroxyl or benzyl bromide end groups) and ethylene oxide or mono-methyl poly(ethylene glycol) (PEGs) were used to prepare a series of PS-co-PD-b-PEO amphiphilic copolymers. Investigations on the association and self-assembly of copolymers in dilute organic and in mixed organic/water solutions have been carried out both by light scattering and microscopic measurements. Nanosized and microsized species have been observed. Their shape depends on the hydrophobic/hydrophilic blocks ratio as well as on the solvent composition. Attempts on stabilizing the morphology of the aggregates/micelles have been made by UV-induced cross-linking of diene entities. It has been found that in some experiments, the stabilization proceeds throughout morphological rearrangement determined by the solvent nature and by the cross-linking protocol.
