摘　要：考察了NBR/PVC共混比和NBR/PVC与EPDM，IIR或PU三元硫化共混物在天那水中的体积变化和物理性能变化。结果表明，当NBR/PVCC以70/30共混时，二元共混物的耐溶剂性能最好；NBR/PVC/PU共混比为50/20/30时，三元共混物耐天那水性能最好，经天那水浸泡后的性能变化很小。

Abstract：The influence of the blending ratio on the Thinner resistance of NBR/PVC was investigated and the volume change and physical property change of NBR/PVC/EPDM,NBR/PVC/IIR or NBR/PVC/PU were also discussed.The results showed that the optimum solvent resistance of binary blend was obtained when the 70/30 blending ratio of NBR/PVC was used;and the best Thinner resistance of triblend was obtained when 50/20/30 blending ratio of NBR/PVC/PU was used.
