A stable, fluid or spreadable, aerobically-hardening adhesive, storable without hardening under exclusion of oxygen, containing polymerizable olefinically-unsaturated compounds and an amount sufficient to initiate polymerization of an organoboron compound initiator, in the form of an aerobically-hardening single-component mixture, consisting essentially of: (a) at least one organoboron compound capable of initiating the polymerization of ethylenically-unsaturated compounds in the presence of oxygen, in an amount sufficient to initiate the polymerization, (b) at least one polymerizable compound containing at least one ethylenic double bond with a molecular weight of between 63 and 10,000 (c) at least one compound capable of inhibiting and/or stabilizing anionic polymerization, in an amount sufficient to inhibit and/or stabilize anionic polymerization, and (d) optionally, other conventional auxiliary substances for aerobically-hardening adhesives. The adhesives harden spontaneously in the presence of oxygen in a short time to give stable adhesive bonds, even in the presence of moisture.
