<p>PCT No. PCT/AT87/00026 Sec. 371 Date Dec. 14, 1987 Sec. 102(e) Date Dec. 14, 1987 PCT Filed Apr. 14, 1987 PCT Pub. No. WO87/06183 PCT Pub. Date Oct. 22, 1987.During the essentially continuous process for producing a polymer plastic, especially a foil or thin sheet (38) containing polymethyl methacrylate, a highly-viscous polymer plastic is first applied to a flat carrier inside a separating layer, whereby regions of the support surface remain free, in the manner of a surface pattern. Next a low-viscosity polymerizable monomer and/or pre-polymer (30) are cast on to this separating layer in such a way that it forms, over the separating layer, a liquid layer, onto which is applied a flat, thread-like support material (32), which may advantageously have a decorative surface and into which the support material (32) is then embedded or impressed. Next after the possible application of further layers consisting of high and/or low-viscosity plastic, especially inside a second separating layer, the thus produced material coating is transferred to the foil (38) or thin sheet, accompanied by polymerization of the plastics contained therein. In this process, the separating layers prevent the support material from coming close to the surfaces of the sheet (38) to be produced, since the highly-viscous plastic contained in the separating layers does not penetrate the porous support material.</p> |
