Popis:	Two-dimensional light scattering and digital imaging studies of the structural evolution in a grat copolymer-homopolymer blend under quasi-static elongation are reported. The graft copolymer consists of a polydisperse elastomeric poly(ethyl acrylate) (PEA) backbone onto which monodisperse thermoplastic polystyrene (PS) chains are grafted. The homopolymer poly(ethyl acrylate) is produced in situ since grafts are not incorporated into every chain. The «quasi-equilibrium» structure of the graft copolymer blend cast from a good solvent exhibits isotropic xscattering (i.e., appearance of a spinodal ring) with an inverse characteristic length q m ≃ 4 μm -1
