Abstract
Micelle formation, thermodynamic equilibrium and compactness of chromo phore-labelled styrene(hydrogenated isoprene) diblock and styrene-(hyd rogenated butadiene)-styrene three-block copolymers in selective solve nt systems have been investigated using nonradiative energy transfer a nd fluorescence quenching techniques. Donor (carbazole) or acceptor (a nthracene) chromophores were randomly attached to the polystyrene part of block copolymers. The relaxation behaviour of micellar solution an d the kinetics of micelle dissociation in various solvent composition and temperature were studied. Copyright (C) 1996 Elsevier Science Ltd.
