2-Cyanoacrylate represented by the formula: ##STR1## wherein R.sup.1 is a 1,2-alkylene group having 2-4 carbon atoms; R.sup.2 is an alkylene group having 2-4 carbon atoms and R.sup.3 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.
2-氰基丙烯酸酯的结构式为:##STR1##其中R.sup.1是具有2-4个碳原子的1,2-烷基基团;R.sup.2是具有2-4个碳原子的烷基基团,R.sup.3是具有1-6个碳原子的烷基基团,这些2-氰丙烯酸酯可以与微量水类似于迄今为止已知的2-氰基丙烯酸酯进行阴离子聚合,所得到的固化产物比迄今为止已知的产物更富有柔韧性。因此,它不仅可用作金属、塑料、木材和陶瓷的即时固化粘合剂,而且尤其适用于橡胶、皮革、布料和纤维等柔性材料的粘合剂。此外,这些2-氰基丙烯酸酯还可用作涂料材料和成型材料。
