TIRE COMPRISING AN ELASTOMERIC POLYMER INCLUDING A FUNCTIONAL GROUP AND CROSSLINKABLE ELASTOMERIC COMPOSITION

摘要

Tire comprising: - a carcass structure of a substantially toroidal shape, having opposite lateral edges associated with respective right-hand and left-hand bead structures, said bead structures comprising at least one bead core and at least one bead filler; - a belt structure applied in a radially external position with respect to said carcass structure; - a tread band radially superimposed on said belt structure; - a pair of sidewalls applied laterally on opposite sides with respect to said carcass structure, - at least one structural element selected from bead filler, sidewall insert, tread underlayer, obtained by crosslinking a crosslinkable elastomeric composition comprising: (a) a crosslinkable elastomeric base comprising at least about 30 phr, preferably from about 50 phr to about 100 phr, of at least one elastomeric polymer including from about 0.05% by weight to about 10% by weight, preferably from about 0.1% by weight to about 5% by weight, with respect to the total weight of the elastomeric polymer, of at least one functional group selected from carboxylic groups, carboxylate groups, anhydride groups, ester groups; (b) from about 2 phr to about 50 phr, preferably from about 5 phr to about 30 phr, of at least one layered inorganic material.
