Abstract:
      The deformation，heat build up and viscoelasticity of SSBR/NdBR and SSBR/NiBR blends under dynamic compression were comparatively studied. The results showed that with the increasing of the additional level of BR，the dynamic compression deformation and tanδ of SSBR/BR blend decreased，the compression fatigue temperature rising，resilience and storage modulus increased，and the loss modulus first decreased and then increased. Compared with SSBR/NiBR blend，SSBR/NdBR blend had a lower compression fatigue temperature rising，compression deformation and tanδ，better deformation recovery ability and lower heat build up.
