摘要： The present disclosure relates to a method for controlling size distribution of formed polymer particles during preparation of aqueous polymer dispersion. The method comprises obtaining an aqueous polysaccharide solution, which comprises about 10 to 40 weight-% polysaccharide containing a free hydroxyl group, such as starch, and polymerising in the polysaccharide solution in the presence of a graft-linking, water-soluble redox system about 30 to 60 weight-% of at least one optionally substituted styrene, about 60 to 30 weight-% of at least one C1-C4-alkyl(meth)acrylate, and 0 to about 10 weight-% of other ethylenically unsaturated copolymerizable monomers. The size distribution of the formed polymer particles is controlled by adjusting viscosity of the polysaccharide solution before the polymerisation to a level less than about 20 mPas. The present disclosure relates also to an aqueous polymer dispersion having the D(99) value less than about 160 nm for polymer particles in the polymer dispersion and its use.
