A process for producing modified cross-linked polymer particles which comprises polymerizing 0.01 to 900 parts by weight of (B) a monomer component containing 50% by weight or more of at least one member selected from the group consisting of aromatic monoalkenyl compounds, acrylic acid esters, methacrylic acid esters, fluoroalkyl acrylates, fluoroalkyl methacrylates, unsaturated carboxylic acids, conjugated diene compounds, vinyl esters and organosilane compounds in the presence of 100 parts by weight of (A) cross-linked polymer particles obtained by polymerizing a monomer mixture comprising 50% by weight or more of at least one cross-linking monomer selected from the group consisting of divinylbenzene, ethylene glycol dimethacrylate and trimethylolpropane trimethacrylate. |
