| 采用乳液聚合法制备单分散交联聚苯乙烯（PS）和α-甲基苯乙烯-丙烯腈共聚物（α-MS-AN）乳胶粒子，并研究其填充NBR和SBR胶料性能。结果表明，当引发剂KPS、乳化剂OP-10和SDS、交联剂DVB质量分别为单体质量的1%，3.3%，6.6%和20％时，可制备出平均粒径为43 nm、玻璃化温度（Tg）为125 ℃的PS纳米微球；当引发剂APS、乳化剂MS-1和交联剂DVB质量分别为单体质量的0.3%，2%~3%和15％时，可制备出平均粒径为47 nm、Tg为152 ℃的α-MS-AN纳米微球。两种填料在NBR和SBR胶料中的最佳用量均为30份；PS填充SBR胶料的物理性能优于其填充的NBR胶料；α-MS-AN填充的NBR胶料物理性能优于其填充的SBR胶料。 |

| Monodisperse crosslinked polystyrene（PS） and α-methyl styrene-acrylonitrile（α-MS-AN） nano-latex particles were prepared by emulsion polymerization，and the physical properties of NBR and SBR filled with nano-latex particles were investigated.The results showed that the average particle size and Tg of PS were 43 nm and 125 ℃ respectively when the addition level of KPS，OP-10，SDS and DVB were 1%，3.3%，6.6% and 20%，respectively；the average particle size and Tg of α-MS-AN were 47 nm and 152 ℃ respectively when the addition level of APS，MS-1 and DVB were 0.3%，2%~3% and 15%，respectively.The optimum addition level of fillers was 30 phr；the physical properties of PS filled SBR was better than those of PS filled NBR；and the physical properties of α-MS-AN filled NBR was better than those of α-MS-AN filled SBR. |
