Abstract:
      The properties of silica and silica/carbon black reinforced single-end and both-end modified solution polymerized styrene-butadiene rubber（SSBR）/butadiene rubber（BR） blend were studied. The results showed that the compatibility between SSBR and silica was significantly improved with the endmodification of SSBR，especially both-end modification，and the comprehensive physical properties and dynamic mechanical properties of SSBR/BR blend were improved. However，the end-modification effect of SSBR didn’t play an effective role in silica/carbon black reinforced end-modified SSBR/BR blend，and the comprehensive physical properties and dynamic mechanical properties of silica/carbon black reinforced endmodified SSBR/BR blend were inferior to those of silica reinforced end-modified SSBR/BR blend.
