Abstract: Bead polymers comprising 80 to 99 % by weight of at least one C1-C18-alkyl ester of methacrylic acid and 1 to 20 % by weight of at least one C1-C18-alkyl ester of acrylic acid, obtainable by polymerisation, at a temperature between 100 and 140 DEG C which is approximately constant over the majority of the polymerisation time, by means of an initiator system comprising at least two peroxidic initiators I having different decomposition temperatures T, at which in each case half of the initiator has decomposed after 1 hour, wherein - the initiator Imin having the lowest decomposition temperature has a decomposition temperature Tmin in the range from 60 to 100 DEG C, - the initiator Imax having the highest decomposition temperature has a decomposition temperature Tmax in the range from 100 to 140 DEG C, the difference between Tmax and Tmin is greater than 10 DEG C, and Imax is a perketal of the formula (I) in which the radicals R and R are identical or different alkyl radicals having 1 to 5 carbon atoms, where R and R can be connected to form a 5- or 6-membered ring, and R is a tert-butyl or tert-amyl radical, and - further initiators In, which can be used if desired and have decomposition temperatures Tn between Tmin and Tmax, in the presence of a protective colloid, with the proviso that from 20 to 80 % by weight of the C1-C18-alkyl ester of acrylic acid is only added after a conversion in the range from 20 to 80 %, based on the amount of monomer employed at the beginning.
