In order, in the case of a moulding composition for the production of sanitary-ware components, comprising a methyl-methacrylate-based syrup and from 50 to 85%, expressed in terms of the moulding composition, of an inorganic filler, to obtain an improvement in the scratch-proofness and the abrasion resistance of the shaped components which are obtained therefrom, it is proposed that the composition furthermore comprise elastomer particles or elastomer particle aggregates having a particle size &#x3c;100 &#x3bc;m in an amount in the range of 5% by weight to &#x3c;20% by weight, expressed in terms of the mass of the syrup.

Moulding compositions for the production of sanitary-ware components

In order to obtain curable molding compositions and shaped plastics articles produced therefrom which have an improved hot-pot resistance, it is proposed that a curable molding composition for the production of shaped plastics articles contains, in addition to a liquid monomeric acrylate component and a particulate inorganic material, the latter in a concentration ranging from 45 to 85 wt % and preferably from 55 to 75 wt %, based on the molding composition, an additional portion comprising a particulate hydrophobic and/or oleophobic plastics material in a concentration of 0.5 wt % or more.

Curable molding composition and shaped plastics articles produced from said molding composition

In order to provide a moulding composition which makes it possible to form shaped components having not only one but two or more visible sides, it is proposed that this composition comprise a methyl-methacrylate-based syrup and up to 85%, expressed in terms of the moulding composition, of an inorganic filler, and that the moulding composition comprise deformable, propellant-filled hollow microspheres having a plastic wall which is essentially insoluble in methyl methacrylate, the proportion by volume of the hollow microspheres to the total volume of the moulding composition being in the 5 to 50 vol. % range.

Moulding compositions for the production of sanitary-ware components having more than one visible side

To improve the resistance to scratching of plastic molded articles comprising a polymer matrix filled with inorganic fillers, the filler content being 50 to 90% by weight in relation to the filled matrix, it is suggested that the filler comprise two filler fractions (a) and (b), wherein the filler fraction (a) has a particle size distribution with 98% by weight of the particles having a particle size .ltoreq.150 .mu.m and is distributed essentially uniformly in the polymer matrix, and wherein the filler fraction (b) comprises particles having a particle size of approximately 300 .mu.m to approximately 3000 .mu.m, wherein the proportion of the filler fraction (b) is approximately 1 to 35% by weight of the total filler content, and wherein the proportion of the filler fraction (b) in an outer surface layer of the molded article is enriched to at least 30% by weight in relation to the total mass of the filled matrix.

Plastic molded articles having a polymer matrix filled with inorganic

In a casting composition comprising a curable syrup which contains a liquid monomer and polymer components optionally dissolved therein, and an inorganic filler which includes a quartz sand product, in order to simplify the production of white molded articles, it is proposed that a product, the individual grain of which consists in the core essentially of quartz and at the surface essentially of .alpha.-cristobalite (low-temperature modification) be selected as quartz sand product.

Casting composition

In a castable, curable composition for producing plastic molded articles, comprising a sirup containing a proportion of acrylic acid monomer and/or derivatives thereof, in order to achieve an improved boiling resistance of the plastic molded articles produced from the composition, it is proposed that a proportion of a further component of the formula (I) ##STR1## which contains an ethylenically unsaturated group of the formula (II)
