| 中文摘要: |
| 以合成的大分子单体香茅醇衣康酸单酯羧酸铵（CIPA）和丙烯酸钠（NaAA）为原料，采用反相乳液共聚法制备改性吸水树脂［P（CIPA-NaAA）］，并对其填充的丁苯橡胶（SBR）性能进行研究。结果表明：P（CIPA-NaAA）的平均粒径约为0.5 μm；与NaAA/SBR硫化胶相比，P（CIPA-NaAA）/SBR硫化胶中P（CIPA-NaAA）分散较好，相容性、吸水性能和物理性能提高。 |
| 英文摘要: |
| The modified water-absorbent resin P（CIPA-NaAA） was prepared by inverse emulsion polymerization and using synthesized macromonomer，the ammonium salt of the monoester of citronellol and itaconic acid （CIPA），and sodium acrylate （NaAA） as raw materials，and the properties of P（CIPA-NaAA）/SBR vulcanizates were investigated.The average particle diameter of P（CIPA-NaAA） was about 0.5 μm.Compared with PNaAA/SBR vulcanizates，the compatibility and dispersion of P（CIPA-NaAA） in P（CIPA-NaAA）/SBR vulcanizates were better，and the water-absorption capability and physical properties were improved. |
