Influence of O rganoclay on Compatibility of Different Ratio of Immiscible (S BR/NBR) Rubber Blend

Blending of poly mers has become a useful techniqu e to produc e and develop material with prope rties superior to those of individual constituent s [۱]. Howe ver, most po lymer blen ds are thermodynamically immiscible and pha se separated upon blen ding [۲]. T his phenom enon during blending causes poore r properties than their individual c onstituents, therefore a third comp onent which is called compatibili zers have been used t o prevent this phenomenon. Recently Nanopa rticles are being used as a compat ibilizer to r educe interfacial tension and improve final pro perties by locating at the interface [۳ ].In this study nanocomposites based on sty rene butadiene rubber (SBR), acrylonitrile butadiene rubbe r (NBR) an d different ratio (SBR/N BR: ۸۰/۲۰, ۲۰/۸۰) of their blend were prepared by melt mixing. Th en the structure and compatibility of the prepared c ompounds were investigated. Me chanical pr operties of the prepar ed samples were also determined and compa red with each other.
