Ternary polymer blends of poly(#945; -methylstyrol), deutereted polystyrene and polyisoprene were investigated on self-assembly and structure formation. The homopolymers were blended in different ratios of weight fraction, spin-coated and annealed at a distinguished tempareture. The multiple length scales were determined with atomic force microscopy (AFM) and grazing incidence small angle scattering with synchrotron radiation (GISAXS) and neutron beam (GISANS). To determine the diffusion of the deutereted component perpendicular to the surface the kinetic measurement were performed with the time-of-flight method and the thin polymer blend films were exposed in a saturated solvent vapour atmosphere. The present work demonstrates the morphology and structure formation depending on the annealing time and the exposure time of the solvent vapour which yields in multiple length scales in a #956; m till nm range.    «
