    • The invention concerns a castable curable compound for the production of plastic mouldings, the compound comprising a syrup containing acrylic acid monomers and/or derivatives thereof. In order to ensure that the mouldings manufactured from the compound have better resistance to boiling, the invention proposes that an additional component of the formula (I) is added, the additional component having an ethylenically unsaturated group of the formula (II) -R5-R6 and/or a group of the formula (III), the syrup optionally also containing a prepolymer, in particular PMMA, as well as 50 to 90 % by wt., relative to the total weight, of a particulate inorganic filler, plus pigments and a radical-initiator system, the viscosity of the final compound being less than 100 Pa s and the ratio of the sum of the contents of the acrylic acid monomers and their derivatives to the sum of the contents of the other components and the PMMA being 99:1 to 30:70 by weight, and the ratio, in the presence of PMMA, of the total content of the other components to the PMMA being at least 5:95 by weight.
