Abstract: A process for producing a viscous epoxy syrup from at least one liquid multifunctional epoxy, comprising the steps of: adding an initiator selected from the group consisting of electron-poor monoisocyanate, photoinitiator and thermal initiator to at least one liquid multifunctional epoxy; mixing the components; polymerizing the multifunctional epoxy such that the viscosity of the resulting epoxy syrup is at least twice as high, preferably at least four times as high and in particular at least ten times as high as the viscosity of the employed epoxy in the unreacted state makes it possible to produce epoxy adhesives having pressure-sensitive properties.
