Abstract
Polystyrene-block-poly(ethylene-co-propylene) solutions in decane have been investigated by dynamic and static light scattering. The dissolu tion of the diblock copolymer in a solvent, which is selective of alip hatic blocks, yields well-defined metastable micellar structures. Thes e structures are converted into equilibrium micelles on heating and ch ange into frozen micelles when cooled. A similar pattern is observed a lso in dioxane, which is a selective solvent for polystyrene blocks.
