Polycyanoacrylate foam is made by mixing together a cyanoacrylate monomer, a liquid foaming agent and a polymerisation initiator. The mixture simultaneously polymerises and foams. The foaming agent is usually an organic compound with a boiling point not higher than 100 DEG C, miscible with the monomer but not a solvent for the polymer. The monomer may be any 2-cyanoacrylate ester compatible with the composition. |
