Abstract: Ultra-fine-grained thermoplastics such as polyolefins, for example, having an average particle size D50 of less than 400 &mgr;m and are present in a mixture along with a filler where the amount of filler material in the mixture amounts to 40 to 90% with respect to the mixture. As such ultra-fine-grained thermoplastics cannot be obtained by means of the normal milling process of if so then only with considerable expenditure, the process for manufacturing ultrafine-grained thermoplastics is performed in such a manner that a mixture containing 10 to 60 wt. % thermoplastics with respect to the mixture and 40 to 90 wt.% filler material with respect to the mixture is ground e.g. in an impact pulverizer, as a result of which thermoplastic particles with an average particle size D50 less than 400 &mgr;m are produced.
