Abstract
The invention relates to a process for preparing an impact-modified plastic, where particles of a crosslinked rubber are produced from a first monomer mixture which has at least 50% by weight of conjugated diene compounds, the rubber particles are added to a second monomer mixture which has at least 85% by weight, preferably at least 90% by weight, in particular at least 98% by weight, of styrene, and the monomers of the second monomer mixture are polymerized. This process can prepare novel and improved impact-modified plastics. Novel impact-modified plastics are also described.
