FIELD: chemistry.
SUBSTANCE: invention relates to a masterbatch comprising a dimeric and/or trimeric cyclic ketone peroxide dispersed in a polymeric matrix with a porosity, expressed as percentage of voids on the volume of the matrix, of 0.1-80 vol%, wherein said masterbatch comprises, per 100 g of polymeric matrix, 1-30 g dimeric and/or trimeric cyclic ketone peroxide and less than 0.20 g saturated hydrocarbons with 17-51 carbon atoms.
EFFECT: invention also relates to a process for the preparation of such a masterbatch and to its use for the modification of polymers in order to control rheological properties.
