Abstract: Polyacrylate graft rubber copolymer B and an impact modified thermoplastic molding composition thereof, where the graft copolymer B is composed of: B1: 50 to 70 wt.-% crosslinked acrylate polymer graft base B1 B2: 30 to 50 wt.-% graft shell B2 comprising a first layer B21 of vinylaromatic monomers, and a second layer B22 of vinylaromatic monomers B21-1 and nitrile monomers B22-2: wherein the particle diameter dw of the graft base BI is 255 to 290 nm; the fraction of B21 is 10 to 26 wt.-%; and the amount of B22-2, is 20 to 30 wt.-%.

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.
