摘要
The present invention relates to a process for producing impact modifiers, impact modified thermoplastic molding compositions and in particular impact modified polycarbonate or polycarbonate/polyester blends having improved resistance to degradation. More particularly the present invention relates to a process for producing polymeric impact modifiers with a core-shell structure made by a multistage process comprising a control and adjustment if necessary of the pH value before and during the recovery step.
