<p>The invention relates to an extrudable or pressable binder composition, comprising: i) at least one binder (C), ii) an agent for controlling the rheology, polymer (P), which is in the form of an emulsion of copolymerised (meth)acrylic acid, branched or straight-chain C1-C22 alkyl (meth)acrylate, optionally with a third monomer of general formula: C(Re)(Rg) = C(Rf)-A1 and, as a further option, with at least one chain-length regulator, (iii) water (E) with a weight ratio of water (E) to binder (C) less than or equal to 0.25, preferably less than or equal to 0.21. The copolymer has the following composition of monomers a), b) and c) and regulating agent in the following weight proportions per 100 weight parts of a) + b) + c):a) 25 - 60 %, preferably 30 to 50 %, b) 40-75 %, preferably 50 to 70 %, c) 0-15 %, preferably 0.5 to 15 % and d) 0 to 5 %, preferably 0 to 0.5 %.</p> |
