Abstract: Polymerizate comprised of a total of a) 50 - 99.98 wt.% of a C1-C12 alkyl(meth)acrylate, b) 0.02 - 10 wt.% of a vinyl aromatic compound, c) 0 - 10 wt.% of an ethylenically unsaturated acid or an ethylenically unsaturated acid anhydride and d) 0 - 40 wt.% of further monomers, wherein the percentage by weight is related to the polymerizate and the polymerizate is obtained by the polymerization of the monomers a) to d) in at least two steps, in which their vinyl aromatic content differs in such a way that the vinyl aromatic content in the step which is rich in vinyl aromatics is at least five times higher than the step which is poor in vinyl aromatics.

Abstract: A process for preserving a mineral moulding by coating the surface of said casting with an aqueous composition containing an aqueous polymer dispersion in which the polymer P in dispersed distribution contains a polymerised ethylenically unsaturated acid of the 2-acrylamide-2-methyl propane sulphonic acid type incorporated in radically polymerised form.

Abstract: Aqueous synthetic resin formulations essentially contain A) from 3 to 75% by weight of one or more synthetic resins which are composed of a) from 50 to 99.9% by weight of one or more unsaturated carboxylic or vinyl esters, b) from 0.1 to 12% by weight of one or more alpha , beta -monoethylenically unsaturated monobasic or dibasic acids or their ahydrides, c) from 0 to 10% by weight of one or more monoethylenically unsaturated acetophenone or benzophenone derivatives, d) from 0 to 35% by weight of one or more other copolymerizable monoethylenically unsaturated monomers, in polymerized form, B) one or more metal cations having a charge of from 2 to 4, in water-soluble form, C) from 0 to 10% by weight, based on the synthetic resin A, or benezophenones or acetophenones which are not monoethylenically unsaturated, D) effective amounts of emulsifiers or protective colloids or a mixture of these active ingredients, E) not less than 5% by weight of water and F) from 0 to 85% by weight of finely divided fillers, and the total amount of the cations B is such that it is capable of neutralizing from 0.2 to 6 times the amount, corresponding to the amount of acid functions incorporated in the form of the monomers b in the synthetic resin A, of their conjugated bases. These synthetic resin formulations are suitable for coating, adhesive bonding, sealing or impregnating.
