Ternary polymer blend films studied with grazing incidence small angle scattering — •J. S. Gutmann1, P. Müller-Buschbaum2, and M. Stamm11IPF Dresden, Hohe Str. 6, 01069 Dresden — 2TU München Physik Department LS E13, James-Franck-Str.1, 85747 Garching

typically multicomponent systems, where two or more main components are mixed in order to achieve synergistic effects. In addition to these main components additives are commonly added in order to act as plastifiers or compatibilizers. We investigated ternary blend systems consisting of two incompatible statistical poly-styrene-stat-para-bromostyrene polymers and one additive, which acts either as a plastifier or as a compatibilizer depending on its molecular weight. While the resulting surface structures are readily probed with scanning microscopy [1], the internal structure of the film is investigated with grazing incidence small angle scattering experiments [2].
