| 摘要 |
A monomer-grafted cross-linked polymer is prepared by the steps of activating a polymer by radiation, quenching the activated polymer so as to effect cross-linking therein, activating the cross-linked polymer by irradiation and contacting the activated cross-linked polymer with an emulsion that includes an unsaturated monomer, an emulsifier and water. The activated cross-linked polymer is contacted with the emulsion for a sufficient time to effect a desired extent of grafting.
