    Abstract: The invention relates to the use of synthetic adhesives for producing corrugated cardboard at relatively low temperatures and high web speeds. The corrugated cardboard comprises a corrugated paper web and a smooth cover web, and the corrugation of the corrugated paper web is generated at paper temperatures lower than 95ºC and at a web speed greater than 150 m/min. Immediately after the corrugation of the corrugated paper web has been generated, a preferably unheated corrugation adhesive is applied in a continuous process and the corrugated paper web is glued to the at least one first cover web. The corrugation adhesive used is an aqueous adhesive dispersion on the basis of at least one synthetic, dispersed polymer having preferably a solids content of more than 40 wt %, selected from acrylate copolymers, copolymers from vinylaromatic compounds and conjugated aliphatic dienes and vinyl acetate/alkylene copolymers, wherein the glass transition temperatures of the polymers are higher than 20ºC and below the surface temperature of the corrugated paper web (preferably by at least 50ºC) to which they are applied.

    Abstract: The invention relates to a method for producing aqueous solutions of acrylic acid polymers by polymerizing acrylic acid in feed mode with a radical starter in the presence of hypophosphite in water as a solvent, wherein (i) water and optionally acrylic acid in acidic, non-neutralized form, optionally one or more ethylenically unsaturated comonomers, optionally aqueous hypophosphite solution, and optionally initiator are introduced, (ii) acrylic acid in acidic, non-neutralized form, optionally one or more ethylenically unsaturated comonomers, aqueous radical starter solution, and aqueous hypophosphite solution are added, (iii) after the end of the acrylic acid feed, a base is added to the aqueous solution, wherein the comonomer content does not exceed 30 wt% with respect to the total monomer content, characterized in that the acrylic acid, the aqueous radical starter solution, and the aqueous hypophosphite solution are added in such a way that, over a time period in which at least 75% of the acrylic acid is converted, the molar ratio x of acrylic acid to phosphorus-bonded hydrogen [AA]/[P-H] has a value x that is constant to ±0.5 and that lies in the range of 0.8 to 2.

    Abstract: The present invention relates to a cationic polymer obtainable by polymerization of at least one cationic monomer, at least one crosslinker and optionally further monomers, such as nonionic monomers, associative monomers and/or chain transfer agents. The cationic polymer has an at least bimodal molecular weight distribution with at least one first peak (P1) and at least one second peak (P2), wherein the first peak has a rather low average sedimentation coefficient of = 10 Sved and the second peak has a rather high average sedimentation coefficient of = 10,000 Sved. The water-soluble polymer components of the cationic polymer are = 25% by weight related to the total amount of cationic polymer. The present invention further relates to a process for obtaining such a cationic polymer as well as to an inverse dispersion, a thickener or a deposition aid, comprising at least one of such cationic polymers.
