RUBBER COMPOSITION CONTAINING GLYCEROL AND FUNCTIONALIZED ELASTOMER AND TREAD THEREOF

摘要

A reinforced rubber composition, used for the manufacture of treads of tyres, includes (a) a functionalized diene elastomer selected from elastomers that are chain-end functionalized, coupled, or star-branched by a group containing a polar functional group having at least one oxygen atom and block elastomers having at least one polar block, (b) glycerol, and (c) a reinforcing filler that includes an inorganic filler. The rubber composition may impart a low rolling resistance to the tyre treads.
