Process for forming concentrates by loading porous polymer particles with a solid substance, wherein the solid substance and the porous polymer particles are mixed in a mixing apparatus in which a vibration field is created, which has a frequency (f) of between 10 and 5000 Hz and an amplitude (A) of between 0.05 and 100 mm. Also concentrates and their use are claimed, which concentrates are obtainable by the process, wherein the concentrates comprise porous polymer particles and solid substances, wherein the solid substances cannot be melted at a temperature below the melting temperature of the porous polymer particle and with the proviso that liquid auxiliaries are absent. |
