    Blends of acrylonitrile butadiene rubber/superior processing/natural rubber and poly(vinyl chloride) Part I. a study of some of the technological properties of NBR/SP rubber/NR/PVC blends
    (Rubber Research Institute. Agalawatta, 1999) De Silva, K.G.K.; Karunanayake, L.; Muttukkrishnan, K.
    The advantage s of using superior processing(SP)rubber in place of natural rubber (NR) in blends with NBR and NBR/PVC is discussed here in derail.various technological properties such as tensile,resilience,hardness,compression set,specific gravity,cross-lind density and resistance to oil were measured and compared. It is advantageous to use SP rubber in place of NR in the above blends probably due to higher cross-link density in the SP rubber component when compared to NR. It may be possible to use the ternary blends of SP/PVC? NBR in manufacture of injection moldable and recyclable products due to their thermoplastic nature

    Improving phase morphology and properties of NR/NBR blends with compatibilizers
    (Rubber Research Institute. Agalawatta, 1998) De Silva, K.G.K.; Lewan, M.
    Two compatibilizing agent have been identified for NR/NBR blend to improve the phase morphology and interfaial adhesion, thereby improving the physical and technological properties. Light and optical microscopy and Nuclear Magnetic Resonance have been used to study the phase contrast and crosslink distribution of the elastomer blends respectively, to suport the observations mode on the improvements in the physical properties of these blends.
