Abstract: A particulate polymer P having an average particle diameter d50 of from 0.1 to 50 mum is prepared by a process in which an emulsion E is prepared fromone or more monomers M, which are polymerizable by free radical polymerization to give the polymer P,water, andat least one protective colloid PCby the action of high shear forces, and the emulsion E is subjected to polymerization in a reactor with the use of a free radical polymerization initiator RI wherein, based on the emulsion E, not more than 75% by weight of the emulsion E (initially taken portion of E) are initially taken in the reactor at the beginning of the polymerization and at least 25% by weight of the emulsion E (feed portion of E) are not fed to the reactor until after the beginning of the polymerization.

Abstract: The invention relates to a method for producing particulate polymers P by radically initiated aqueous emulsion polymerization, wherein at least one ethylenically unsaturated monomer is emulsified by means of a dispersing agent in an aqueous medium and polymerized by means of a radical polymerization initiator in the presence of a stable N-oxyl radical so that an aqueous polymer dispersion is obtained. According to the inventive method: a) a peroxide, a hydroperoxide and/or an azoic compound are used as a radical polymerization initiator, whose molar solubility at 25 DEG C and 1 bar in water is greater than or the same as the corresponding molar solubility of tert-butyl hydroperoxide in water and whose decomposition temperature in a polymerization medium is
