| Abstract: |
| The NBR/PVC/organomontmorillonite(OMMT) nanocomposites were prepared by emulsionco-precipitation technique and direct mixing technique respectively.The curing characteristics，microstructure，dynamic properties and thermal stability of the obtained nanocomposites were investigated.The results showed that ts and t90 of NBR/PVC/OMMT nanocomposites reduced significantly as OMMT could accelerate the curing rate of NBR remarkably；the NBR/PVC/OMMT nanocomposites prepared by both emulsion co-precipitation technique and direct mixing technique were intercalationtype nanocomposites；and the NBR/PVC/OMMT nanocomposites prepared by emulsion co-precipitation technique featured more uniform dispersion of OMMT and higher storage modulus，Tg and pyrolytic temperature as well as better dynamic properties and thermal stability when compared to that prepared by direct mixing technique. |
