| 中文摘要: |
| 采用原位生成法制备聚甲基丙烯酸钠（PNaMAA）/NBR纳米复合材料，研究混炼工艺、硫化剂DCP用量、丙烯酸（MAA）与氢氧化钠的摩尔比和甲基丙烯酸钠（NaMAA）的理论生成量对复合材料物理性能的影响。结果表明，采用先快速加酸后分次加碱的混炼工艺，DCP用量为1.5份，MAA与氢氧化钠的摩尔比为1.5：1，NaMAA的理论生成量为30份，混炼胶在160 ℃×t90条件下硫化，可获得物理性能优异的PNaMAA/NBR纳米复合材料。 |

| The nano-composites of in-situ polymerized sodium methylacrylate(PNaMAA)/NBR were prepared and the effects of the mixing procedure，the level of DCP，the molecular ratio of MAA/sodium hydroxide and the theoretical yield of NaMAA on the physical properties of composites were investigated.The results showed that the PNaMAA/NBR nano-composite with the optimum physical properties was obtained by using 1.5 phr of DCP，MAA/sodium hydroxide with molecular ratio of 1.5：1，30 phr of NaMAA for theoretical yield，160 ℃×t90 cure and mixing procedure，in which the acid was rapidly added at first，and the alkali was added in batches later. |
