Abstract: In a process for preserving a mineral molding by coating the surface of the mineral molding with an aqueous composition comprising an aqueous polymer dispersion, the dispersed polymer P comprises an ethylenically unsaturated acid of the 2-acrylamido-2-methylpropanesulfonic acid type polymerized into it in free-radically polymerized form.

Abstract: Paper and paperboard of high dry strength are produced by adding a dry strength enhancer to the paper stock and dewatering the paper stock with sheet formation by using as the dry strength enhancer a mixture of a cationic polymer which contains as characteristic monomers copolymerized units of (a) diallyldimethylammonium chloride, (b) N-vinylamine or (c) a substituted or unsubstituted N-vinylimidazoline and has a K value of not less than 30, and natural potato starch which is converted into a water-soluble form by heating in an aqueous medium at above the gelatinization temperature of natural potato starch in the absence of any oxidizing agents or alkali.
