Abstract:
The present invention relates to a core-shell particle which has a core, a first shell and, where appropriate, a second shell, where: i) the core encompasses, based on its total weight, at least 75.0% by weight of (meth)acrylate repeat units; ii) the first shell has a glass transition temperature below 30° C.; iii) the second shell present where appropriate encompassed, based on its total weight, at lest 75.0% by weight of (meth)acrylate repeat units; iv) the first shell encompasses, based on its total weight, the following constituents; E) from 92.0 to 98.0% by weight of (meth)acrylate repeat units and F) from 2.0 to 8.0% by weight of styrenic repeat units of the general formula (I) where the radicals R1 to R6 are defined according to the Description and the percentages by weight of E) and F) give a total of 100.0% by weight, v) the radius of the core-shell particle inclusive of any second shell present, measured by the Coulter method, is in the range from above 160.0 to 240.0 nm; a process for preparing core-shell particles, to a moulding composition comprising core-shell particles, and to the use thereof.
