摘要： A vulcanized elastomeric composition of matter comprises the reaction product of a sulfur-containing reagent with an anionic living polymer, the reagent being selected from the group consisting of R3—Si—S—R′—X, where R can all be the same or different and is selected from the group consisting of alkyls having from 1 to 8 carbon atoms, cycloalkyls having from 3 to 11 carbon atoms, or an arylene having from 6 to 14 carbon atoms, and X is a halogen, to form a R3—Si—S—R′ ended polymer; a filler; processing oil; and a cure package containing a deprotecting agent and at least one sulfur cure accelerator. A method for making a vulcanized elastomeric composition of matter comprises terminating a living anionic polymer with a sulfur-containing reagent selected from the group consisting of R3—Si—S—R′—X, where R can all be the same or different and is selected from the group consisting of alkyls having from 1 to 8 carbon atoms, cycloalkyls having from 3 to 11 carbon atoms, or aryls having from 6 to 14 carbon atoms, R′ is an alkylene having from 1 to 8 carbon atoms, a cycloalkylene having from 3 to 11 carbon atoms, or an arylene having from 6 to 14 carbon atoms, and X is a halogen, to form a R3—Si—S—R′ polymer having a protected mercapto group; deprotecting the mercapto group prior to or during vulcanization of the composition, and attaching the mercapto group to a polymer backbone of one of the polymers. A method is also provided for reducing hysteresis and the invention provides improved pneumatic tires.

摘要： The invention provides a process for producing a modified conjugated diene based polymer which attains favorable interaction between a rubber component and carbon black and/or silica, thereby improving dispersibility of the fillers, and which exhibits excellent properties such as heat-buildup-suppressing performance, fracture characteristics, and wear resistance; a modified conjugated diene based polymer produced through the process; a rubber composition containing the diene polymer; and a tire produced from the rubber composition and exhibiting the above properties. The process for producing a modified conjugated diene based polymer includes a step (a) of reacting a silicon compound with a conjugated diene based polymer having an active end so that the reaction takes place at the active end, the silicon compound having a protected primary amino group in the molecule thereof and a bi-functional silicon atom to which a hydrocarbyloxy group and a reactive group including a hydrocarbyloxy group are bonded, to thereby modify the active end, and a step (b) of performing condensation reaction which involves the compound having a bi-functional silicon atom, in the presence of a titanium compound serving as a titanium-based condensation-accelerating agent.
