To modify the NBR rubber roll which has poor abrasion and chemical resistance, NBR/PVC blends were prepared in various composition ratios. First of all, their miscibility and vulcanization characteristics were investigated. Their abrasion and chemical resistant properties and physical properties were also studied. DSC thermograms for NBR/PVC blends show only one Tg in the entire composition range, demonstrating a perfect miscibility. In the vulcanization characteristics tested by rheometer, maximum torque decreases as PVC contents increased. In the investigation of physical properties of NBR/PVC blends, hardness increases and elongation decreases along with the increasing contents of PVC. On the other hands, tensile strength increases with the increasing contents of PVC up to 11.1 wt. %, and then decreases with higher contents of PVC. While the abrasion resistance of NBR/PVC blends was similar to that of NBR itself, the chemical resistance of NBR/PVC blends was superior to that of NBR.
