Polymer synthesis

Polymer synthesis
In the polymer synthesis area we develop synthetic methods for the production of well-defined model compounds.

Polymer-colloid Composites
Polymer-colloid composites are synthesized as core-shell particles consisting of an inner solid and inorganic core surrounded by a soft polymer shell. A new "grafting to" technique, developed in our laboratory, allows the functionalization of silica particles with anionically-produced polymers. Cyclic Polymers
Although macrocycles are a common by-product in many polymerization and polycondensation reactions, the specific synthesis of cyclic polymers is much less common. Our goal is to obtain thermally stable, cyclic polymers of high purity, controlled molecular weight and with a narrow molecular weight distribution. The synthetic strategy uses anionic polymerization for the preparation of α,ω-difunctional polymers and subsequent ring closure under highly diluted conditions. The chemical modification of the chain ends of the remaining linear polymers allows the efficient separation from their cyclic counterparts.

Supramolecular Polymers
The building blocks of supramolecular polymers are held together by relatively weak intermolecular interactions such as hydrogen bonds, ionic interactions or metal ligand interactions. The reversible bonds permit the self-healing of structural damages. The success of this process depends on different conditions. One of these is self-assembly. Only when suitable bonding motives fit together, a repair can take place successfully.
