摘要： 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 65 000 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.

摘要： The invention relates to finely divided starch-containing polymer dispersions, which can be obtained by the radically initiated emulsion polymerization of ethylenically unsaturated monomers in the presence of at least one redox initiator and starch, wherein the ethylenically unsaturated monomers used are (a) 30 to 60% by weight of at least one optionally substituted styrol, (b) 1 to 60% by weight of at least one acrylic acid-C1-C12-alkyl ester and/or methacrylic acid-C1-C12-alkyl ester, (c) 0 to 10% by weight of at least one other ethylenically unsaturated copolymerizable monomer, and the starch used is (d) 15 to 40% by weight of at least one degraded starch having a molar mass Mw of 1000 to 65000 g/mol, wherein the sum (a) + (b) + (c) + (d) = 100% and relates to the total solid matter content, and wherein the polymerization is carried out in the presence of at least 0.01% by weight, relative to the monomers used, of at least one terpene-containing polymerization regulator. The invention further relates to a method for producing the finely divided starch-containing polymer dispersions by means of the emulsion polymerization of monomers (a), (b) and (c) using redox initiators in the presence of (d) degraded starch and at least 0.01% by weight, relative to the monomers used, of at least one terpene-containing polymerization regulator, and to the use of the finely divided starch-containing polymer dispersions as a sizing agent for paper, paperboard and cardboard.
