| 摘要 |
The invention relates to a process for preparing an impact-modified plastic based on crosslinked rubber particles, where (a) an aqueous dispersion or suspension of particles of a crosslinked rubber is produced from a first monomer mixture which has less than 50% by weight, preferably less than 5% by weight, in particular less than 2% by weight, content of conjugated diene compounds; (b) where appropriate, the dispersion or suspension is precipitated, giving an aqueous rubber particle mixture with water content of at least 5% by weight; (c) the dispersion or suspension of the rubber particles or the aqueous rubber particle mixture is added to a second mixture which comprises at least one other monomer, and (d) the monomers of the second mixture are polymerized. The invention further relates to a plastic obtainable by the process. |
