Abstract: The invention relates to the production of mouldings based on a particulate material as additive and an aqueous binding agent containing an acrylate polymer, the additive being moistened with the binding agent, converted into the desired shape and subsequently dried, characterised in that a binding agent is employed whose binder is an acrylate polymer whose glass transition range is relatively high and which is built up from (A) predominantly methyl methacrylate, (B) a minor amount of (meth)acrylic acid, (C) if desired, a minor amount of an alkyl ester of acrylic acid and (D) if desired, a small amount of other specific polymerisable compounds.
