| Abstract: |
| 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. |
