Abstract
Self-reinforced, thermoplastically moldable sheets made from poly(meth)acrylate having at least two layers which differ in their filler content. The ratio between the elongation at break of the layer with higher filler content and the elongation at break of the layer with lower filler content is less than 1.5. The poly(meth)acrylate sheets can serve as a semifinished product for producing sanitary items, such as bathtubs, shower trays or washbasins, preferably by thermoforming, without the need for any other reinforcing layers sprayed on or otherwise applied after molding.
