A composition comprises a cyanoacrylate polymer and a protected amine. A method comprises: providing a shaped model comprising a cyanoacrylate polymer; preparing an investment having a cavity that corresponds to the shaped model; and heating the shaped model to sufficient temperature that the cyanoacrylate polymer depolymerizes and volatilizes. A hardenable material may be cast in the investment to provide a replica of the shaped model. A curable composition comprises: a cyanoacrylate monomer; a free-radical photoinitiator; and a protected amine, wherein the curable composition is free of compounds that initiate anionic polymerization of the cyanoacrylate monomer at ambient temperature. A method of curing the curable composition is also disclosed.
