Abstract

The invention relates to a process for the comminution of bulk materials comprising synthetic polymers which do not have an elastomeric behavior by mechanical, thermal or electromagnetic loading of the bulk materials, which comprises treating the bulk materials, before and/or during the loading, with oxidants which have a redox potential of greater than 1.5 V or subjecting them to corona, UV or plasma treatment without complete oxidation of the synthetic polymer taking place.
