Abstract

In this work we discuss the self-assembling behaviour in solution of a block copolymer, dextran-block-polystyrene, in the presence of homopolystyrene (PS) which allows to decrease the hydrophilic fraction f of the mixture. Dynamic and static light scattering experiments have been carried out in water-miscible solvents (DMSO and THF) to probe the formation of supramolecular structures. Results have been compared to those obtained with a block copolymer solution having the same hydrophilic fraction f. Interestingly, the morphology of the self-assembled structures was the same for a given value of f.
