NEW MULTIPLE-CONSTITUENT MIXTURES CAPABLE OF FREE-RADICAL POLYMERIZATION AND THEIR USE

摘要

Mouldable multiple-constituent mixtures capable of free-radical polymerization containing ethylenically unsaturated polymerizable compounds admixed, if desired, with soluble and/or insoluble fillers or other auxiliary substances, and an activator system which can be initiated by the introduction of oxygen are characterized in that they contain an activator system which can be initiated by the introduction of atmospheric air, based on the following main components: N-alkyl-substituted tert.-aryl amines with at least one aliphatic CH bond in the alpha position, metallic compounds which are at least partially soluble in the system and accelerate drying of unsaturated oils, and compounds of weak carboxylic acids with pKS values less than approximately 0.9 which are hydrolysed to free carboxylic acids on contact with moisture. Also described is the use of these multiple-constituent mixtures as aerobically curing adhesive systems, in particular in the form of a 1-component adhesive package with long storage life, and their use as surface coatings or for plastic mouldings.
