  • Processes for preparing multimodal polymer particle compositions
    Patent number: 6989410
    Abstract: 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.

  • Processes for preparing impact modifier powders
    Patent number: 6900254
    Abstract: Processes for preparing a powdery high rubber impact modifier containing two or more populations of polymer particles having a total rubbery weight fraction of greater than 90 weight percent is provided. Also provided are various methods of preparing aqueous polymer particle dispersions having two or more populations of polymer particles having a total rubbery weight fraction of greater than 90 weight percent. These dispersions are spray-driable into a powder and are useful for increasing the impact strength of various matrix resins.
