Nanosponge Formation from Organocatalytically Synthesized Poly(carbonate) Copolymers

Advanced organocatalytic synthesis methods were employed to prepare linear poly(carbonate)s with control over functional group incorporation and molecular weight. Pendant allyl or epoxide groups served as reaction partners in thiol–ene click or epoxide–amine reactions with ethylene oxide-containing cross-linking groups to form a panel of six novel poly(carbonate) nanosponges with cross-linking densities ranging from 5, 10, and 20% via an intermolecular chain cross-linking approach.
