    Abstract: Aqueous synthetic resin formulations containing A) from 3 to 75% by weight of one or more synthetic resins, B) one or more organic compounds having two or more hydrazide groups, C) from 0 to 10% by weight, based on the synthetic resin A, of benzophenone or acetophenone or of one or more acetophenone or benzophenone derivatives which are not monoethylenically unsaturated or of a mixture of these active ingredients, D) effective amounts of emulsifiers or protective colloids or of a mixture of these active ingredients, E) not less than 5% by weight of water and F) from 0 to 85% by weight of finely divided fillers, with the proviso that the total amount of the monomers d polymerized in the one or more synthetic resins A and of component C is from 0.05 to 10% by weight, based on the one or more synthetic resins A, and the ratio of the number of moles of hydrazide groups of component B and the number of moles of the aldehyde and keto groups of the monomers c polymerized in the one or more synthetic resins A is from 0.01 to 2. These synthetic resin formulations are suitable for coating, adhesive bonding, sealing or impregnating.

    Abstract: Light-weight building panels based on mineral fibres A and thermoplastic binders contain 1 to 25% by weight, relative to A, of a copolymer B having a glass transition temperature from 70 to 105 DEG C and built up essentially from 50 to 98% by weight of methyl methacrylate I, 2 to 50% by weight of one or more acrylates II of C1-C8-alkanols and 0 to 2.5% by weight of one or more crosslinking monomers III as binders, 0 to 150% by weight of fillers C and, relative to B, 0.2 to 15% by weight of one or more amines F of the general formula in which R is C8-C18-alkyl or C8-C18-alkenyl, U and V are C2-C4-alkylene, X and Y are hydrogen, C1-C18-alkyl or C2-C18-alkenyl and n and m are integers from 0 to 10, or acid addition salts thereof.

    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.
