摘要： It has been unexpectedly found that greatly improved properties for tire rubbers, such as lower hysteresis, can be attained by coupling the rubber with both a tin halide, such as tin tetrachloride, and a silicon halide, such as silicon tetrachloride. Even better characteristics for use in tire tread compounds can be realized by asymmetrically coupling the rubbery polymer. This invention more specifically discloses a coupled rubbery polymer which is particularly valuable for use in manufacturing tire tread compounds, said coupled rubbery polymer being comprised of (1) tin atoms having at least three polydiene arms covalently bonded thereto and (2) silicon atoms having at least three polydiene arms covalently bonded thereto.
