New publications on C,H insertion crosslinking (CHIC)

Two new publications have emerged from our work on C.H insertion crosslinking (CHIC). Martin Körner describes his theoretical work to better understand the process and Anne-Katrin Schuler reports on her efforts to generate CHIC polymers via polymer analogous reactions.

We use photochemically and thermally reactive polymers with groups that can insert into C,H bonds to crosslink the material and to bind to surfaces. The result are surface attached polymer networks of variable thickness and high stability against delamination.

Usually high gel contents are reached after short reaction times but in other cases also long induction periods were found. His simulations shed a light on the overall process which can now be even predicted for new systems.

Anne-Katrin Schuler has found a way to generate surface attached polymer networks from polymers that were functionalized along polymer analogous reactions. In her example a polyether was decorated with benzophenon groups and she also showed ways to generated microstructures from this material.
