ABSTRACT OF THE DISCLOSURE: The present invention relates to a casting resin made from an acrylic-acid ester in which a large proportion of finely dispersed fillers is mixed. Accord- ing to the invention, the casting resin also contain a polymeric organosilicon compound which is the reaction product of a salt of (meth)acrylic acid with a copolymer of monomeric elements containing functional and non-functional groups. The funtional groups in the copolymer are one or more alcoxysilyl groups and one or more (meth)acryloxysilyl groups. Also polymerized into the copolymer is at least one functional comonomer having an ethylenically unsaturated arrangement and additionally, if necessary, a copolymer from the vinylcarboxylic-acid ester and (meth)acrylic-acid ester group. The addition of such a polymeric organosilicon compound to a casting resin known per se causes substantial reduction in the viscosity of the resin which can be used to produce sanitary article mouldings.
