Zusammenfassung:A multimodal polymer particle composition containing two or more populations of polymer particles having a total rubbery weight fraction of less than 90 weight percent is provided. Also disclosed is a process for preparing multimodal polymer particle compositions that can be dried to a powder. Multimodal polymer particle dispersions are disclosed for preparing impact modifiers that can be dried to a powder. Also provided are polymeric compositions having a matrix resin component and impact modifiers prepared from multimodal polymer particles.
