The invention relates to a method for producing an aqueous polymer dispersion having a polymer solids content of &#x2267;50% by weight by carrying out the radically initiated aqueous emulsion polymerization of ethylenically unsaturated compounds (monomers). The inventive method is characterized in that: a) a mixture is provided in a polymerization vessel and contains a partial quantity 1 consisting of: deionized water, 0.001 to 0.5 parts by weight of a polymer with a weighted average particle diameter of &#x2266;100 nm; 0.0001 to 0.1 parts by weight of dispersants, and 0.5 to 10 parts by weight of monomers, and the monomers are polymerized with a conversion of &#x2267;80% [polymerization step A], and; b) afterwards, a monomer emulsion containing partial quantity 2, which consists of deionized water, 0.1 to 5 parts by weight of dispersants and 90 to 99.5 parts by weight of monomers, is fed under polymerization conditions to the obtained reaction mixture [polymerization step B], whereby; c) the total amount of the monomers used for the polymerization is equal to 100 parts by weight, and the total amount of deionized water is &#x2266;100 parts by weight.

Method for producing an aqueous polymer dispersion

The present invention relates to water soluble radiation activatable polymer resin formulations which are suitable to modify the absorption properties of fibrous materials and the polymer obtained by such radiation activatable polymer resins and the method of preparing such polymer. Fibrous materials made with radiation activatable resin formulations according to this invention are especially suitable for use in disposable absorbent articles.
