The compatibility of hydrogenated poly(butadiene-co-acrylonitrile) (HNBR) with poly(vinyl chloride) (PVC) was investigated in the complete composition range. Dynamic mechanical spectroscopy, d.s.c, and phase-contrast microscopy indicated that the blends are miscible at the segmental level. Depending on composition, a wide spectrum of tensile properties may be obtained. The maximum energy for tensile failure was observed at about 40 wt% rubber content. Tg and the blend modulus dependence on composition supports the view that moderate interactions are present leading to synergism. The overall blend properties suggest that the system does not have microheterogeneities observed for the non-hydrogenated copolymer NBR/PVC blends at a comparable acrylonitrile content.
