Abstract: A process for preparing a thermoplastic polymer composition or a thermoplastic polymer blend, comprising: —from 20 to 80% by weight of at least one water-moist elastomer component A containing up to 40%, preferably up to 30% by weight of residual water, —from 20 to 80% by weight of at least one thermoplastic polymer B, —from 0 to 40% by weight of at least one further polymer C, and —from 0 to 60% by weight of additive(s) D, by mixing the elastomer component A with the thermoplastic polymer B and, if present, the further polymer C and, if present, the additive(s) D in an extruder, comprising the steps of precipitating the elastomer component A, and mechanical dewatering of the elastomer component A leads to improved salt-free products.
