Abstract: Aqueous polymer dispersions containing I a film-forming dispersion polymer as the disperse phase and II from 5 to 40% by weight, based on the total solids content of I and II, of a fully or partially neutralised, water-soluble copolymer comprising a) from 50 to 80 mol% of an olefinically unsaturated mono- or dicarboxylic acid, an anhydride of these acids or a mixture of these monomers, b) from 20 to 50 mol% of a C3- to C12-alkene, styrene or a mixture of these monomers, and c) from 0 to 10 mol% of further monomers which can be polymerised by means of free radicals, in the aqueous phase, give powders on spray drying. The polymer dispersions and the powders are suitable as binders for water-resistant polymer plasters and paints and as adhesives or adhesive components.

Abstract: A concrete tile (I) is claimed, which is coated with a copolymer (A) with Tg -25 to +30 deg.C, derived from (a) 0.1-10 wt.% monomer of formula R1CH=CR2-CO-X-R3-Z-CHR4R5 (III), (b) 85-99.9 wt.% at least 2 monomers of the type (1-24C alkyl) (meth)acrylates, vinyl esters of 1-20C carboxylic acids, up to 20C vinylaromatics, 3-6C unsatd. nitriles, vinyl halides and/or 2-8C non-aromatic hydrocarbons with olefinic double bond(s), and (c) 0-10 wt.% other Sn-free comonomers; R1, R2 = H or 1-4C alkyl; R3 = 1-20C bridging gp.; R4 = -COR6, -COOR6 or CN; R5 = H, -COR9, -COOR9 or CN; X = O or NR7; Z = single bond, CH2, O, NR8 or -OCO-; (with R6-R9 = H, or 1-12C alkyl, aryl, alkaryl or aralkyl). Also claimed is a process for the prodn. of (I), by application of an aq. prepn. contg. (A) to at least one surface of the green concrete, and drying the prepn. by hardening the concrete. More specifically, monomer (a) is acetylacetoxyethyl (meth)acrylate, acetylacetoxybutyl (meth)acrylate, cyanoacetoxyethyl (meth)acrylate, 1,1-dibenzoyl-2-(meth)acrylamidoethane, 1-benzoyl-1-acetyl-2- (meth)acrylamidoethane, or ethyl alpha-benzoyl-beta-(meth) acrylamidopropionate, and (b) are vinylaromatics or (1-8C alkyl) (meth)acrylates; (I) is coated with a prepn. contg. copolymer (A) and up to 450 wt.% mineral additives (B) and/or colour pigments (C) (w.r.t. amt. of A); another layer of the aq. prepn. is applied to the hardened tile and dried; the amt. of prepn. used is such that the total amt. of dry coating is 50-500 g/m2.
