摘要：Mouldable multiple-constituent mixtures capable of free-radical

polymerization, which may also be multicomponent systems with long storage life,containing ethylenically unsaturated polymerizable compounds admixed, if desired, withsoluble and/or insoluble fillers or other auxiliary substances, and an activator systemwhich can be initiated by the introduction of oxygen are characterized in that they areapplied in the form of at least weakly concentrated material containing an activatorsystem which can be initiated by the introduction of atmospheric air, based on thefollowing main components: N-alkyl-substituted tert.-aryl amines with at least onealiphatic CH bond in the alpha position, metallic compounds which are at least partiallysoluble in the system and accelerate drying of unsaturated oils, and weak carboxylic acidswith pKS values less than approximately 0.9. Preferably, the multiple-constituentmixtures ready for application have a minimum viscosity of at least 50 to 100 mPa.s. Theinvention also concerns the use of activator systems of these multiple-componentmixtures for controlled hardening, at a predetermined pot life, of olefinically unsaturatedsystems by means of atmospheric air and ambient temperature or only moderately

elevated temperatures.
