摘　　要：研究白炭黑和白炭黑/炭黑并用补强单、双末端基改性溶聚丁苯橡胶(SSBR)/顺丁橡胶(BR)并用胶的性能。结果表明:SSBR末端基改性,尤其是双末端基改性,能够显著提高SSBR与白炭黑的相容性,从而提高SSBR/BR并用胶的综合物理性能和动态力学性能;SSBR的末端基改性效果在白炭黑/炭黑并用时不能有效发挥,白炭黑/炭黑并用补强末端基改性SSBR/BR并用胶的综合物理性能和动态力学性能均逊于白炭黑补强末端基改性SSBR/BR并用胶。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.
