    Abstract: Adhesives comprising polyvinyl ether copolymers having a weight-average molecular weight > 10,000, which are composed of a) from 0 to 95% by weight of vinyl ethers of the formula I H2C = CH-O-R, b) from 5 to 100% by weight of hydrophilic vinyl ethers of the formula II H2C = CH-O-R , and c) from 0 to 30% by weight of further monomers, in which R is a C1-C10-alkyl group and R1 is an aliphatic or cycloaliphatic radical which may be substituted by hydroxyl groups or interrupted by nonadjacent groups -Y-, where Y is an oxygen atom, a sulphur atom, a group NR or N R R X , in which R and R independently of one another are a hydrogen atom or a C1-C4-alkyl group, and X is a counteranion, and the molar ratio of carbon atoms to the sum of groups Y and hydroxyl groups in the aliphatic or cycloaliphatic radical is from 1.01:1 to 6.5:1.

    Abstract: A method is claimed for using cationically stabilised aq. polymer dispersions (PD) as binders for moulded prods. based on finely divided materials with a negative surface charge (M). These dispersions contain (A) a dispersed copolymer (A) with a static Tg of 40-110 deg. C, based on (a) 30-80 pts. wt. styrene, (b) 20-70 pts. wt. (1-8C alkyl) (meth)acrylate(s) and (c) 0-10 pts. wt. other radically copolymerisable monomers, and (B) as dispersant, a mixt. of prim., sec. and/or tert. organic mono-amine(s) with at least 8 C atoms and acid addn. salts thereof. Also claimed are (i) polymer dispersions (PD) as above; (ii) moulded prods. based on materials (M) and binders (PD); (iii) rectangular moulded sheets based on (M) and (PD), with a length and breadth of 30-70 cm and a thickness of 1-20 mm; (iv) a process for the prodn. of mouldings (ii), by suspending material (M) in water, adding dispersion (PD), precipitating copolymer (A) onto material (M) by adding bases or salts of multivalent anions, placing the mixt. obtd. in a mould, removing water, and drying; (v) moulded prods. obtd. by this process.

    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.
