摘要： The present invention describes a process for the surface finishing of materials via application of specific polymethacrylate layers. The polymethacrylate layers are composed of blends of at least two (co)polymers of polymethacrylates, and specific “reactive monomers” are present here in a polymerized mixture which forms the polymethacrylate layer. At the application temperature established, these form a chemical and, where appropriate, also a physical bond to the substrate, and therefore have adhesion-promoting action.

摘要： The invention relates to a method for producing a thermoplastic plastic film. According to said method, the thermoplastic plastic is melted and transported in an extrusion installation comprising an extruder, an extrusion nozzle with a wide-slot delivery opening and a chill roll, which is fixed to a roll system and then leaves the delivery opening of the extrusion nozzle in the form of a flat melted web. Said melted web is then applied to the chill roll and is cooled. The invention is characterised in that it uses an extrusion installation, in which the distance between the delivery opening of the extrusion nozzle and the surface of the cooled roll does not vary by more than +/−50 μm during the operating time. The invention also relates to a film of this type and to uses of the latter.
