| Abstract: | This paper discussed the mechanical properties and the morphologies of PVC/NBR/CRternary blends.The results of DMA,SEM and TEM indicated that NBR was agood compatibilizer for blends.Addition of small amounts(3% or 4%)NBR improved theimpact strength of blends and caused the shift in Tg of PVC and CR to lower temperaturecompared with that of pure PVC and CR, demonstrating that the interaction between thetwo phases had been enlarged. |
