Abstract
A curable composition includes a hydrogen-bonded prepolymer, a plasticizer that includes an alkyl benzoate or an alkyl phenyl ketone, and, optionally, a crosslinking agent. The plasticizer promotes a high extent of crosslinking and provides a more positive health and safety profile than the incumbent plasticizer, furfural. A cured resin and a method of forming it are described.
