| Abstract: |
| Using lauryl methacrylate （LMA） and butyl metheacrylate （BMA） as monomers，the high oil-absorbing resins（poly LMA-co-BMA） were synthesized by suspension polymerization method.The oil swellable rubbers were prepared with EPDM and LMA monomer or poly LMA-co-BMA，and their properties were investigated.The results showed that，compared with that filled with oil-obsorbing resins，the oil absorbing property of oil swellable rubber filled with LMA monomer was better.The optimum addition level of LMA monomer was 30 phr and the oil absorbing property was excellent.Compared with that filled with LMA monomer，the physical properties of oil swellable rubber filled with oil-absorbing resins were better.When the mass ratio of LMA and BMA was 1∶2，and the addition level of oil-absorbing resins was 20 phr，the physical properties of oil swellable rubber were better. |
