    Abstract: A finely divided, starch-containing polymer dispersion which is obtainable by free radical emulsion polymerization of ethylenically unsaturated monomers in the presence of at least one redox initiator and starch, wherein (a) from 0 to less than 40% by weight of at least one optionally substituted styrene, (b) from greater than 60 to 100% by weight of at least one C1-C12-alkyl acrylate and/or C1-C12-alkyl methacrylate, (c) from 0 to 10% by weight of at least one other ethylenically unsaturated copolymerizable monomer, are used as the ethylenically unsaturated monomers, the sum (a)+(b)+(c) being 100% and being based on the active monomer content and (d) from 15 to 40% by weight of at least one degraded starch which has a molar mass Mw of from 1000 to 65000 g/mol, based on the total weight of solids content of components (a)+(b)+(c)+(d), are used as the starch, and the polymerization being carried out in the presence of at least 0.01% by weight, based on the monomers used, of at least one terpene containing chain-transfer agent, and in which the polymer dispersion optionally comprises an aluminium compound. The use of the finely divided, starch-containing polymer dispersions as sizes for paper, board and cardboard is also claimed.

    Abstract: The present invention relates to a process for producing corrugated fiberboard from plies of paper which each have a grammage of 70 to 200 g/m2 and of which at least one ply of paper is obtained by a process comprising the addition of (A) 0.25 to 5 wt %, based on dry paper stock, of at least one cationic polymer comprising vinylamine units, and (B) 0 to 5 wt %, based on dry paper stock, of at least one polymeric anionic compound, to a paper stock, draining the paper stock by sheet formation, coating the paper web obtained with (C) 0.1 to 3 wt %, based on dry paper stock, of at least one starch and drying the coated paper web, wherein the polymeric anionic compound is selected from a polymeric anionic compound (B1) and a polymeric anionic compound (B2), wherein said polymeric anionic compound (B1) is obtainable by copolymerizing a monomer mixture comprising, preferably consisting of, (a) at least one monomer (a) selected from acrylamide and an N-vinylcarboxamide of the formula where R1 and R2 are each H or C1 to C6 alkyl, (b) at least one acid-functional monoethylenically unsaturated monomer and/or its alkali metal, alkaline earth metal or ammonium salts (b), and (c) optionally one or more monoethylenically unsaturated compounds (c) other than said monomers (a) and (b), and (d) optionally one or more compounds having at least two ethylenically unsaturated double bonds in the molecule, and said polymeric anionic compound (B2) is the hydrolysis product of said polymeric anionic compound (B1) whose carboxamide moieties have been partly or wholly hydrolyzed into amino groups, and also the corrugated fiberboard thus obtained and its use in the manufacture of packaging boxes from corrugated fiberboard.
