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.
