Solidification of Polyurethane Model Foams via Catalyst Drainage from a Secondary Foam

Front Cover: The generation of model monodisperse polyurethane foams with controlled morphology is achieved via the drainage from a secondary foam containing catalyst into a first foam produced without catalyst, and the homogeneity and reproducibility of the final foams is revealed via detailed structural characterization using X-ray microtomography.
