Abstract

The fast growing cosmetic market and the need for innovative products with new or combined properties lead to the development of a large variety of new complex polymer materials. The variations which can be achieved by modifying the monomer composition or the method of synthesis are very useful to produce (co)polymers with peculiar properties. The demand in characterization is then very important to understand the molecular structure of these new products in order to relate them with the observed properties aiming at the establishment of structure-property relationships. Such knowledge allows for optimization of the parameters of the synthesis and consequently the final application properties. The aim of this work was to develop analytical methods and tools to comprehensively characterise the heterogeneities of acrylate- and methacrylate-based copolymers. The focus of the method development was on multidimensional chromatographic techniques that allow the different parameters of molecular heterogeneity (e.g. molar mass distribution, MMD, chemical composition distribution, CCD) to be described quantitatively.

Der schnell wachsende Markt für kosmetische Erzeugnisse und der Bedarf an innovativen Produkten mit neuen und verbesserten Eigenschaften führen zur Entwicklung von immer komplexeren Polymerstrukturen. Die Strukturvariationen können durch unterschiedliche Monomerkombinationen oder durch unterschiedliche Polymerisationsverfahren erreicht werden. Sie führen häufig zu Copolymeren mit ungewöhnlichen Eigenschaften. Für das detaillierte Verständnis der molekularen Struktur dieser neuen Produkte bzw. für die Erarbeitung von Struktur-Eigenschaftsbeziehungen sind neue und bessere Charakterisierungsverfahren erforderlich. Nur so können Syntheseparameter und letztendlich die Produkteigenschaften gezielt optimiert werden. Das Ziel der vorliegenden Arbeit war die Entwicklung von analytischen Methoden zur umfassenden Charakterisierung der molekularen Heterogenität von Copolymeren auf der Basis unterschiedlicher Acrylate und Methacrylate. Der Fokus lag dabei auf der Entwicklung von mehrdimensionalen chromatographischen Methoden, die es gestatten, die unterschiedlichen molekularen Parameter (z. B. Molmassenverteilung, MMD, und chemische Heterogenität, CCD) quantitativ zu bestimmen.German
