Abstract
The conformational transition of block copolymers has been studied until now using measurements of the second virial coefficient and the radius of gyration (light scattering) or of the intrinsic viscosity. In this paper the conformational transition of polystyrene–poly(methyl methacrylate) diblock copolymers with temperature is studied using measurements of the critical concentration c** which is obtained in the dynamic state (viscometry) and in the static state (UV measurements).
