Thermoresponsive Bottle-Brush Polymers (IMAGE) Technical University of Munich (TUM) Caption Upon heating thermoresponsive molecular brushes with propylene oxide/ethylene oxide copolymer side chains in aqueous solution split off water molecules. Depending on the structure of the polymer the molecular structure collapses at the cloud point, resulting in water-insoluble polymer coils, which form loose or compact clusters depending on the residual water content.
