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.
