Abstract: The production of polymer powder (I) suitable for the modification of mineral binder building materials, involves drying an aqueous polymer dispersion which forms films with a Tg of not above 30 degrees C, where before drying, the dispersion is treated with drying agents (IIa) which have a liquefying action on the mineral binder when it is mixed with water and ready for use; after drying, the powder (I) is treated with finely divided solid additive(s) (IIIa) which have a solidifying action on the binder/water mix. Alternatively, the dispersion is treated with solidifying driers (IIb) before drying, and the dried powder is treated with finely divided solid additives (IIIb) which have a liquefying action on the mix. Also claimed are: (i) polymer powder (I) obtained by this process; (ii) mineral binders containing (I); and (iii) dry mortar preparations containing 20-60 wt% mineral binder, 0.1-20 wt% (I) and up to 25 wt% conventional additives, the remainder consisting of sand, fillers, pigments and natural and/or synthetic fibres.

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 appts. to coat a moving substrate surface (6) with a flow mass (2,2'), from a supply chamber (7,8), is structured so that the chamber (7,8) partially covers the material (6) surface flanked by a sealing gap (14) and an exit gap (18) at the entry and outlet sides. The supply chamber is divided into an initial holding chamber (7) and a main holding chamber (8), to prevent the development of air bubbles in the coating medium (2,2'). The divider (10), between the chamber sections (7,8), also sets the gap (15) between the chamber and the moving web (6).
