Beschreibung
Zusammenfassung:	Process for preparing crosslinked copolymer granules, containing from 50 to 99.5 mole% of monovinyl monomer units and from 0.5 to 50 mole% of crosslinking monomer units, by free radical polymerization in aqueous dispersion, characterized in that the the polymerization reaction is carried out in the presence of 0.01 to 10 millimoles per mole of monomer of a reaction moderating modifier comprising one or more acetylenically or allylic unsaturated organic compounds incorporated into the monomer.
