Abstract
The thermoreversible fcc-bcc transition in concentrated block copolymer micellar solutions was discussed. It was found that temperature-induced changes in micellar characteristics, particularly the mean aggregation number was quantified in dilute solutions. It was demonstrated that the softening of the intermicelle potential with decreasing aggregation number was the key feature. Analysis shows that the observed phase boundary was in excellent agreement with simulations of highly branched star polymers.
