    Abstract: A concrete roof tile is coated with an unfilled or aggregate- and/or pigment-filled film of a copolymer containing (a) from 0.03 to 2% by weight of tin in the form of a polymerizable organotin compound (b) from 0.5 to 5% by weight of (meth)acrylic acid, (meth)acrylamide and/or vinylsulfonic acid and (c) from 0.1 to 5% by weight of carbonyl-containing monomers crosslinked with certain dicarboxodihydrazides, besides (d) at least two (meth)acrylic esters of C1-C8alkanols and/or styrene as copolymerized units in such an amount and such mixing ratios that the copolymer has a glass transition temperature of -15 to +10 DEG C. prior to crosslinking.

    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.

    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.
