Abstract: Aqueous polymer dispersions (I), containing a radical copolymer (CP) with an alkali metal ion content (GA) of not more than 0.5 wt.%, based on (A) 20-65 wt.% vinylaromatic monomer(s), (B) 35-80 wt.% comonomer(s) with two conjugated double bonds and (C) 0-10 wt.% other comonomers with at least one double bond. Also claimed are (i) aqueous polymer preparations containing (I) and finely divided pigment in amounts of up to 60 vol.% (IIA) or 20-45 vol.% (IIB); (ii) substrates coated with a film of (I) or (II), and (iii) a process for the production of (I) by radical- initiated aqueous emulsion polymerisation of the above comonomers, with the addition of ammonia and/or organic amine to increase the pH of the dispersion medium.

Abstract: Prodn. of modified mineral building materials is effected using an aq. dispersion contg. polymer particles of wt. average dia. 100-300 (pref. 100-200)nm, the polymer being free radically polymerised and being of each of the following 3 types of monomers; (a) up to 5 wt.% (meth)acrylate acid or salts; (b) up to 5 wt.% (meth)acrylamide; and (c) 90-97.5 wt.% other non-ionic, ethylenically unsaturated monomers, pref. styrene and/or butadiene. The dispersions are claimed, as are powders obtd. by spray drying of the dispersions.

Abstract: The method involves guiding a substrate web (10) in perpendicular to an application device (40) by two rollers (18, 20). Vibration (94) of the substrate web is produced perpendicular to a conveying direction (16) or a vibration of a housing of the application device. The vibration of the housing is directed perpendicular to the conveying direction of the substrate path. The vibration of the substrate web is produced downstream in relation to the application device by the roller (20). An independent claim is also included for a device for coating of the substrate web.
