Abstract (en)
[origin: WO2005002830A1] The invention relates to a method for the production of a plastic body provided with a microstructured surface by producing a composite from a carrier layer consisting of a thermoplastic or thermoelastic plastic, provided with one or several structural layers. Said method is characterised in that the structural layer(s) contain(s) 1 - 100 wt.- % of a polymethacrylate-moulding material which contains from 80 - 100 wt.- % of radically polymerised methylmethacrylate units and 0 - 20 wt. % additional radical comonomers which can be polymerised and which have an average molecular weight (average weight ) Mw of 30.000 g/mol - 70.000 g/mol and, optionally, a mixture containing up to 99 wt. % polymethacrylate moulding material containing 80 - 100 wt. % radically polymerised methylmethacrylate units and from 0 - 20 wt. % additional radical comonomers which can be polymerised and have an average molecular weight (average weight) Mw of 90.000 g/mol -200.000 g/mol and the structural layer and/or the structural layers are microstructured, after the production of the composite, according to known structuring methods. The invention also relates to a plastic body produced according to the inventive method and to the uses thereof.
