<jats:title>Abstract</jats:title><jats:p>Polybutadiene was solubilized in dilute solutions of styrene/butadiene/styrene block copolymers in selective solvents for polystyrene. The formed mixed micelles gave rise to a permanent turbidity of the solution. The systems were investigated by viscometry and light scattering. Using simplifying assumptions about the shape of the micelles, the micellar weights (up to 10<jats:sup>10</jats:sup>) and sizes (particle diameter up to 300 nm), as well as the average volume fractions of the polymer in the space occupied by a micelle (≈ 0,8–1,0) were estimated.</jats:p>
