In dieser Arbeit wurden Kleinwinkel Neutronenstreuexperimente an einer dreikomponentigen Polymermischung bestehend aus einer binären kritischen Mischung aus Polystyrol und Polybutadien und dem entsprechenden symmetrischen Diblockcopolymer untersucht. Die Analyse der kritischen Exponenten ergeben sehr genau den Übergang vom Molekularverhalten bei hohen Temperaturen zu den von thermischen Fluktuationen dominierten Bereichen bei tiefen Temperaturen sowie den Übergang von der 3d-Ising zu der Lifschitz der kritischen Universalitätsklasse. Neu gefunden wurde ein Doppeltkritischer Punkt, der das Zweiphasengebiet zu hohen Diblock Konzentrationen hin abschließt, sowie eine Tröpfen und bikontinuierliche Mikroemulsion. Eine detaillierte Analyse der Gi...
