| Abstract: |
| 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. |
