    Abstract: 1. A light-weight building board which is based on mineral fibers and a thermoplastic binder, may furthermore contain fillers, fireproofing agents and water repellents and contains, as the binder, from 4 to 20 %, based on the weight of the mineral fibers, of a polymer having a glass transition temperature fo from 60 to 1108C and consisting of from 60 to 100 % by weight, based on the copolymer, of (meth) acrylates of alcohols of 1 to 4 carbon atoms and from 0 to 40 % by weight of (meth) acrylonitrile and/or styrene, which board additionally contains a salt of a carboxylic acid of 12 to 36 carbon atoms with a polyvalent metal.

    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.

    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.
