Abstract:
An elastomeric composition includes at least one elastomeric diene polymer, at least one thermoplastic polymer, and at least one polymer comprising functional groups. The at least one thermoplastic polymer comprises a main hydrocarbon chain. Hydrophilic groups are linked to the main hydrocarbon chain. The functional groups are reactive with the hydrophilic groups. The composition may also include at least one reinforcing filler. The at least one reinforcing filler may include carbon black, silica, or both carbon black and silica. The composition may further include a silica coupling agent, a sulfur-based vulcanizing agent, or both a silica coupling agent and a sulfur-based vulcanizing agent. A tire for vehicle wheels including at least one element including an elastomeric material, where the at least one element include the composition, is also disclosed.
