<p>The invention relates to a process for the production of filled plastic mouldings based on polyalkyl methacrylate having a granite effect in a shaping polymerisation chamber under the conditions of free-radical polymerisation, where metal-coloured, platelet-shaped phyllosilicates SSK in particle form having a particle size in the region from 20 to 500 mu m are distributed in a casting resin suspension comprising A) 20 - 80 parts by weight of a liquid PMMA polymer precursor, B) 0 - 75 parts by weight of a non-metallized, particulate filler, C) 0 - 5 parts by weight, based on the sum of A) and B), of a polymerisable organosilicon compound and D) 0 - 2 parts by weight of one or more pigments or colorants, in proportions of from 1 to 35 parts by weight, based on the sum of A) and B), the free-radical polymerisation is carried out to completion, and the moulding is subsequently demoulded.</p> |
