    • Adhesive composition consisting of .alpha.-cyanoacrylate, one or more sulphonic acid derivatives as stabilizers and conventional additives. The stabilizers are sulphonic acid derivatives having the general formula ##STR1## in which R.sup.1 is a trimethylsilyl group, R.sup.2 a halogen atom, an alkyl group, a perfluoroalkyl group, a cycloalkyl group or an aryl group or R.sup.1 and R.sup.2 together, accompanied by cyclization, represent a group of the general formula ##STR2## in which Z is a substituted or unsubstituted phenylene radical. Preferred are combinations of compounds in which in one R.sup.1 is a trimethylsilyl group and in the other R.sup.1 and R.sup.2 form the aforementioned ring group. (Dihydroxy)-organylboranes and bis(dihydroxyboryl)-derivatives can be used as costabilizers. The storage stability obtained with the stabilizers according to the invention is excellent, without impairing the setting rate and the strength of the bonds obtained.
    • 由α-氰基丙烯酸酯,一种或多种磺酸衍生物作为稳定剂和常规添加剂组成的粘合剂组合物。 稳定剂是具有通式(Ⅰ)的磺酸衍生物,其中R1是三甲基甲硅烷基,R2是卤素原子,烷基,全氟烷基,环烷基或芳基,或者R1和R2一起, 伴随着环化,代表一组通式为其中Z为取代或未取代的亚苯基的通式(II)。 优选的化合物的组合,其中一个R 1是三甲基甲硅烷基,另一个R 1和R 2形成上述环基。 (二羟基) - 有机硼烷和双(二羟基硼烷)衍生物可用作成本稳定剂。 用本发明的稳定剂获得的保存稳定性优异,而不损害所得到的粘合剂的凝固速率和强度。
