AbstractMicellar solutions of polystyrene-poly(acrylic acid) block copolymers are studied in the jammed regime. Increasing attraction between soft spheres, both the rheology and dynamic light scattering show a re-entrant liquid to glass transition. The dynamics was also investigated at an attraction strength above the re-entrant transition line. Increasing concentration of sticky soft spheres in this region, the particle dynamics shows a remarkable extended logarithmic decay. The theoretical predictions of mode coupling theory agree well with our results.

Soft glasses produced after the cessation of shear flow exhibit persistent residual stresses. Mode coupling theory of the glass transition explains their history dependence in terms of nonequilibrium, nonlinear-response relaxation of density fluctuations.
