  • 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.
    Type: Grant

  • Plastics additives: improved process, products, and articles containing same
    Publication number: 20010056150
    Abstract: An improved process for preparing an aqueous dispersion of plastics additive polymer particles using emulsion polymerization of one or more ethylenically unsaturated monomers in an aqueous medium in the presence of a free radical redox initiator system is described. The free radical redox initiator system uses an oxidizing agent, a reducing agent, and a combination of metal ion species. The plastics additive polymer particles are useful as processing aids and impact modifiers in PVC articles.
