Abstract: A double-sided adhesive tape having a first outer impact-adhesive side and a second outer side that can be heat activated, comprising an at least two-layer product structure comprising the layers A and B. Layer A is an impact-adhesive layer chemically cross-linked by means of thermal initiation or an impact-adhesive carrier layer chemically cross-linked by means of thermal initiation. Layer B is a layer on the basis of a thermoplastic plastic. Layer A and layer B are in direct contact with each other, and the surface of layer B that is in direct contact with layer A has been corona- or plasma-pretreated. The double-sided adhesive tape is characterized in that the corona or plasma pretreatment is performed in an atmosphere comprising nitrogen, carbon dioxide, or a noble gas or a mixture of at least two of said gases.

Abstract: Adhesive tape having at least two layers A and B laminated directly on one another, with at least one or both layers A or B being an adhesive, and the interfaces of the layers A and B laminated on one another being subjected to a physical method, the physical method being selected from the group consisting of corona discharge, dielectric barrier discharge, flame pretreatment and plasma treatment, before the layers are laminated to one another, with the two methods differing from one another.

Abstract: Method for the solvent-free production of acrylate adhesive masses, which comprises (a) continuously coating a mixture, containing one or more photoinitiators and a monomer mixture comprising (i) 70 to 100% by weight compounds selected from the group consisting of (meth)acrylic acid and the derivatives thereof in accordance with the formula where R1 is H or CH3 and R2 is an alkyl chain having 2 to 20 carbon atoms; (ii) 0 to 30% by weight of olefinically unsaturated monomers having functional groups; and (iii) optionally additional components, or a prepolymer of said monomer mixture on a process carrier; b) polymerizing the coated mixture by applying radiation to the coated sections of the process carrier using visible or ultraviolet light; (c) separating the polymer product from the process carrier and forming the polymer product; (d) transferring the polymer product into a mixing device; (e) mixing the polymer product with additional components in a mixing device; and (f) further processing the polymer p

Abstract: A multirange indicator is proposed which permits quantitative dose determination of high-energy actinic radiation, where the dose for different wavelength ranges can be respectively determined in parallel. To this end, the multirange indicator has two indicator systems designed with mutually corresponding properties, thus eliminating any mutual distortion of the results of the dose measurements. The first indicator system is based on a photolatent Lewis acid or photolatent Lewis base, and the second indicator system is based on a polysubstituted triphenylmethane dye. Both the multirange indicator and its use for the production of various dose-measurement devices are described.
