Chemistry of Polymers

The research projects of the previous years resulted in the finding that the properties of coatings and compound materials could be designed more functional and improved in quality if one succeeded in integrating additional "functions" and avoiding compatibility problems occurring. This can be achieved for instance through a targeted chemical modification of the polymers involved in the composite structure and/or with customised additives. The department "Chemistry of polymers" rises to this challenge.

By means of chemical and physicochemical methods of combining polymer structural elements with different inherent properties a new type of polymer systems shall be created.

Head of Department

"The collaboration of various disciplines is what fascinates me most about polymers. Chemistry is equally important as physics. The composition of formulations and the chemical modifications are as crucial as the interactions between the compounds. The smallest particles or the substitution of functional moieties may have enormous impacts. We aim at understanding and utilizing the structure-property relationships of polymers and additives. By combining and modifying materials of different resources, we want to contribute to the progress towards sustainability and alternative materials."

ADVANCED POLYMER SYSTEMS

Currently, the work of our department focuses on three subjects. On the one hand we are coupling polymers of synthetic and biological origin in a suitable way with each other (polymer-analogous implementation, reactive spacer groups, block copolymers). Synthesis of special polymers is also intended. On the other hand we are thoroughly investigating the role and the effect of surface active agents in stabilising aqueous polymer dispersions as advanced coating materials. We would like to understand them better than to date, in order to influence film or layer formation in a targeted way. Thirdly, we are modifying the properties of polymers using functional additives such as plasticisers and flame retardants. Here above all we focus on bio-based systems. In this regard we can already draw on a wealth of experience. In addition, methods for characterising the molecular structure of polymers are gradually established.

Synthesis and chemical modification

The usage properties of materials consisting of polymers, irrespective of the fact if synthetic or natural polymers are meant, are considerably determined by the inherent properties of the polymers…

Polymer dispersions
