    Abstract: AKD cellulosic composition obtainable by flowing a stream of a cellulosic suspension through a shearing device and in which a molten alkyl ketene dimer (AKD) is metered in to the stream of cellulosic suspension in or prior to the shearing device. The AKD cellulosic composition is particularly suitable in the manufacture of sized paper and paperboard.

    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.
