    Description / Table of Contents: Investigations on chemical coupling of heterogeneous polystyrene-polybutadiene blends were carried out using an organic sulfonylazide. The coupling process was realized in the melt mixing process on a laboratory melt kneader. The efficiency of the coupling agent was evaluated by IR-spectroscopical, microscopical, and dynamic-mechanical analysis and by mechanical properties of the blends. The graft copolymers forming in the melt cause an increase of the stress-strain properties and the impact strength of the blends.
    Notes: Es wurden Untersuchungen zur chemischen Kopplung heterogener Polystyrol-Polybutadien-Blends bei Einsatz eines organischen Sulfonylazids während des Schmelzemischens im Laborinnenmischer angestellt. Die Wirksamkeit des Kopplungsagens wurde anhand infrarotspektroskopischer, mikroskopischer und dynamisch-mechanischer Analysen sowie anhand des merchanischen Eigenschaftsbildes der Belends beurteilt. Die sich in der Schmelze bildenden Pfropfcopolymeren führen zu einer Erhöhung der Phasenwechselwirkungen un dami zu einer Verbesserung der Festigkeits- und Zähigkeits-eigenschaften der Blends.
