Kinetic glass transition in a micellar system with short-range attractive interaction

We show that percolation and structural arrest transitions coexist in diffe rent regions of the phase diagram of a copolymer-micellar system and relate them to short-range intermicellar attraction. The intermediate scattering function shows a nonergodic transition along a temperature and concentratio n dependent line. Analyses show a logarithmic time dependence, attributed t o a higher-order glass transition singularity predicted by mode-coupling th eory, followed by a power law.
