Abstract: An antifoaming agent, based on an oil-in-water emulsion in which the oil phase accounts for from 5-50% by weight of the emulsion, where the oil phase includes: (a) at least one selected from the group consisting of (a1) an alcohol of not less than 12 carbon atoms and (a2) a C1-C36-carboxylic acid, a distillation residue; (d) a component including (d1) a polyglyceryl ester and (d2) a C18-C30 alkyl behenate, wherein the component (d) accounts for 1-80% by weight of the oil phase of the emulsion.

Abstract: The invention relates to a finely divided, starch-containing aqueous 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 the ethylenically unsaturated monomers comprise (a) from 30 to 65% by weight of acrylonitrile and/or methacrylonitrile, (b) from 35 to 60% by weight of at least one C1-C12-alkyl acrylate and/or at least one C1-C12-alkyl methacrylate, (c) from 0 to 35% by weight of at least one other ethylenically unsaturated copolymerisable monomer, in which the sum of (a), (b) and (c) totals 100%, and in which the aqueous polymer dispersion comprises, (d) from 10 to 55% by weight of an ionic tapioca starch, in which the weight of (d) is based on the total solids of components (a), (b), (c) and (d) of the aqueous polymer dispersion. The invention also relates to a process for the manufacture of the finely divided, starch containing aqueous polymer dispersions and also to the use of said finely divided starch containing aqueous polymer dispersions as a size for paper, board and cardboard.
