Abstract

The application of thermal and spectroscopic techniques in the characterisation of chemically modified materials is illustrated with several examples: ethylene vinyl acetate (EVA) copolymers which had been hydrolysed under alkaline conditions, amosite asbestos fibres which had been reacted with alkyldimethylchlorosilanes, and a polymeric composite material which had been affected by moisture.

Zusammenfassung

Anhand verschiedener Beispiele wird die Anwendung thermischer und spektroskopischer Methoden zur Charakterisierung chemisch modifizierter Materialien gezeigt: Ethylenvinylacetatkopolymere (hydrolysiert unter alkalischen Bedingungen), Amosit Asbestfasern (nach zuvoriger Reaktion mit Alkyldimethylchlorsilanen) und polymère Verbundwerkstoffe (nach zuvoriger Einwirkung von Feuchte).
