Abstract
Modification of lithium-terminated elastomer intermediates by reaction under anionic conditions with 1,3,2-dioxastannolanes provides tin-containing elastomers with improved hysteresis properties. In specific examples, modification of a lithium-terminated styrene-butadiene rubber with a dioxastannolane derived from reaction of dibutyl tin(IV)oxide with an alkyl-substituted 1,3-pentane provides tin-modified SBRs with lowered tan delta properties. Such modified elastomers are useful in making tread portions of pneumatic tires.
