Abstract
Described are heat-activatable promoters for treating the surfaces of metals or synthetic materials (plastics) prior to bonding, containing from 0.1 to 10% by weight of a carbonyl compound having at least one activated double bond, from 5 to 30% by weight of a polymer having functional groups, from 0 to 10% by weight of further auxiliary materials, as well as one or more organic solvent(s) to make 100% by weight. The invention further relates to a process for producing the heat-activatable adhesion promoter and the use thereof for the surface treatment of polymer fibers.
