Research Activities

The research activities in the Analytical Department are integrated in the main fields of research of the Institute of Polymer Research. They especially include the characterization of structure, reactivity, morphology and interactions in functionalized linear and branched polymers, in copolymers, in heterogeneous polymer blends, crosslinked polymer systems and in composites by NMR (H. Komber), MALDI-TOF-MS (K. Sahre), IR/Raman (K.-J. Eichhorn/D. Fischer), Thermoanalysis (L. Häußler), SEC with different detectors and A4F (A. Lederer).

Actual Materials:
Modified Hyperbranched Polymers and Dendrimers
Polymers for Organic Electronics
Hydrogels and Brushes
Polyesters and block copolymers
Nanocomposites
