    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: For moulded bodies, obtainable by impregnation or coating of base mouldings built up mainly from mineral fibres, non-fibrous mineral fillers and starch, with compositions which contain, as binders, copolymers consisting of a) 60 to 95 % by weight of methyl methacrylate (monomer I> b) 5 to 40 % by weight of acrylate and/or methacrylic acid (monomers II> c) 0 to 35 % by weight of one or more acrylates of a C1- to C8-alkanol (monomers III> d) 0 to 5 % by weight of copolymerisable, olefinically polyunsaturated monomers (monomers (IV) and e) 0 to 5 % by weight of other copolymerisable monomers (monomers V) in the polymerised form, the proportions by weight of the monomers I, II, III and V are selected within the indicated limits in such a way that a polymer built up only from these monomers would have a glass temperature of from 60 to 125 DEG C.
