2-Cyanoacrylate represented by the formula: [Figure] wherein R1 is a 1,2-alkylene group having 2-4 carbon atoms; R2 is an alkylene group having 2-4 carbon atoms and R3 is an alkyl group having 1-6 carbon atoms, said 2-cyanoarylates can be anion-polymerized with a slight quantity of water similarly to hitherto known 2-cyanoacrylates, and the resulting cured product is richer in flexibility than the hitherto known ones. Therefore, it is not only useful as an instant-setting adhesive for metals, plastics, wood and ceramics but also is particularly useful as an adhesive for flexible materials such as rubber, leather, cloth and fiber. Further, said 2-cyanoacrylates are also useful as a coating material and a molding material.
