METHOD FOR MAKING A POLYCARBONATE MULTI-LAYER STRUCTURE

摘要

The invention relates to a method for producing a composite comprising at least one first polymer layer and a second polymer layer, each being made of a polycarbonate polymer based on bisphenol A, an intermediate layer being disposed between the first polymer layer and the second polymer layer, comprising the following steps: a) the intermediate layer is applied to at least one partial region of the first polymer layer, b) optionally the intermediate layer is dried, c) on the side on which the intermediate layer is disposed, the first polymer layer is coated with a liquid preparation containing a solvent, or a solvent mixture, and a polycarbonate derivative based on a geminally disubstituted dihydroxydiphenyl cycloalkane, the preparation covering the intermediate layer, d) optionally, after step c) a drying step is carried out, e) after step c) or step d), the second polymer layer is placed onto the first polymer layer, covering the intermediate layer, and f) the first polymer layer and the second polymer layer are laminated to each other under pressure, at a temperature of 120ºC to 230ºC and for a defined time period.
