| abstract |
The invention concerns a method for producing a planar polymeric stack, said stack comprising at least first and second (co-)polymer layers (20, 30) stacked one on top of the other, the first underlying (co-)polymer layer (20) not having undergone any prior treatment allowing it to crosslink, at least one of the (co-)polymer layers initially being in a liquid or viscous state, said method being characterised in that the top layer (30), referred to as the top coat (TC), is deposited on the first layer (20) in the form of a pre-polymer composition (pre-TC), comprising at least one monomer and/or dimer and/or oligomer and/or polymer in solution, and in that it is then subjected to a heat treatment capable of causing a crosslinking reaction in the molecular chains within said layer (30, TC). |
