    摘要: A process for preparing a polymeric material grafted throughout its bulk is provided. A polymer having finely divided particles is blended with silica and maintained in a fluidized bed. The polymer is activated by passing ozone uniformly through the blend to initiate incipient labile sites in the molecular structure of the polymer. The polymer is then reacted with an ethylenically unsaturated ionogenic monomer to graft polymerize the monomer onto the polymer. The grafted polymer may then be converted to a salt form by reacting with alkaline compounds. The resultant powders can be fused into any desired shape by conventional polymer plastic processes.
