Abstract: The present invention is directed to a functionalized elastomer comprising the reaction product of a living anionic elastomeric polymer and a polymerization terminator of formula I where n is an integer from 1 to 3; X is a tetravalent organic group selected from a hydrocarbyl group of formula CmH2m-2 where m is an integer from 1 to 10, a group of formula II where R3 is C1 to C10 alkane diyl, and the group of phenyl diyl; R1 and R2 are independently selected from C1 to C10 alkyl, and a group of formula III where R4, R5 are independently C1 to C10 alkyl, and R6 is C1 to C10 alkanediyl; or R1 and R2 taken together with their common Si atom form a five-membered heterocyclic ring selected from formulas IV and V where R7 is from C1 to C10 alkyl.

Abstract: A shear band and a non-pneumatic tire is described which includes a ground contacting annular tread portion; a shear band, and a connecting web positioned between a hub and the shear band. The shear band is preferably comprised of a three-dimensional spacer fabric having a first and second layer connected by connecting members. The three-dimensional spacer fabric has a defined depth. The three-dimensional spacer structure further includes a plurality of cells formed between the connecting members, and wherein one or more of the cells are filled with a filler material. The filler material may be foam or a thermoplastic elastomer.
