摘要： A process for the manufacture of paper having a high dry strength and a low wet strength, by treating the surface of the paper with an aqueous solution of an alkaline earth metal salt of, or a mixture of an alkaline earth metal salt and an alkali metal salt of a polymer of (a) from 91 to 100% by weight of acrylic acid and/or methacrylic acid and (b) from 0 to 9% by weight of acrylonitrile, methacrylonitrile, acrylamide, methacrylamide, vinyl acetate, maleic anhydride, diisobutylene, an ester of acrylic acid and/or an ester of methacrylic acid, which has a viscosity of from 5 to 100 mPas in 2% strength aqueous solution at 20.degree.C, and drying the impregnated paper. The polymer is generally employed in an amount of from 1 to 4% by weight, based on dry paper, and increases the dry strength of the paper without substantially increasing the wet strength.

摘要： A process for the emulsion polymerization of olefinically saturated monomers comprises heating the reaction mixture by the addition of heated water or steam. A process to reduce the wall coating and coagulate formation during the radically initiated polymerization of olefinically unsaturated monomers in aqueous emulsions at a polymerization temperature of 35-120 deg C comprises heating the reaction mixture to at least the polymerization temperature by the addition of heated water and/or steam.
