Metallocen/MAO-Katalysatoren sind effiziente Werkzeuge in der Lösungspolymerisation von Olefinen. Sie zeichnen sich durch hohe Aktivitäten aus und ermöglichen es, die Polyolefine in bezug auf Mikrostruktur, Schmelzpunkt und Molmasse maûzuschneidern. Nach Heterogenisierung der Metallocen/MAO-Katalysatoren lassen sich diese an etablierte Slurry-und Gasphasenprozesse hervorragend adaptieren.Die mit heterogenisierten Metallocen/MAO-Katalysatoren hergestellten Polyolefine zeichnen sich zudem durch eine mittels des Trägermaterials einstellbare Morphologie aus. Das Trägermaterial fungiert als Templat, wobei die Morphologie der Polyolefine aus Replikaten der Ausgangsform der verwendeten Trägerteilchen gebildet wird.

Monitoring and control of industrial or biotechnological processes invariably require reliable and fast analytical systems. Twodimensional spectral fluorescence allows real time automatic measurements directly inside the process and provides a continuous stream of information compared to discrete information available from repeated sampling and offline analysis. Normally, chromatographic molasses desugarization processes are typically monitored with a combination of an onlinerefractometer, polarimeter and the measurement ofdensity and conductivity. Additional information ofthe separation profile could be obtained by multiple sampling during the separation cycle followed by offline laboratory analysis. An optical sensor (BioView®) allows online fluorescence measurements for a continuous monitoring directly at the outlet of the separation columns. It was the aim to predict the amino acid serine during the chromatographic cycle. Based on fluorescence, it was possible to monitor a fluorophor, which eluted a few minutes before the serine fraction during molasses desugarization. The application of fluorescence measurements for monitoring and control of chromatographic separation process may improve yield and purity of the separating fractions and can lower the costs for the next downstream processing of by-products.
