Foreword/Avant-propos. Polymer stabilization - present status and possible future trends. Nitroxyl radicals and nitroxylethers beyond stabilization: radical generators for efficient polymer modification. Macromolecular reactions in polymer blends: Interchain effects. New rheological developments for reactive processing of poly(e-caprolactone). Ester-interchange reactions catalyzed by tin compounds in reactive processing: NMR contribution via reactions with model compounds. Biodegradable materials by reactive extrusion: from catalyzed polymerization to functionalization and blend compatibilization. Polymer degradation during processing. Polymer ageing: Physics, chemistry or engineering? Time to reflect. Modeling of reactive systems in twin screw extrusion: challenges and applications. Process Monitoring of polymers by in-line ATR-IR, NIR and Raman spectroscopy and ultrasonic measurements. Thermal oxidation of cellulose investigated by chemiluminescence. The effect of magnesium and calcium carbonates and of different pH. Spectroscopic probes for real-time monitoring of polymer modification and degradation reactions.
