Water- and Moisture-sensitive Polymeric Releasing System by Hydrolysis of Acetal Moieties Coexisting with Acidic Units

摘要

A methacrylate monomer containing acetal and benzalde-hyde-derived moieties was copolymerized with a sulfonic acid monomer, The copolymer underwent hydrolysis by neighboring effects to release benzaldehyde molecules upon contact with pure water and moisture in aqueous DMF solution and in the solid state.
