Abstract
A rubber compound comprising at least one polymer base with cross-linkable unsaturated chain, a reinforcing filler, a vulcanization system and an interaction agent between the polymer base and the reinforcing filler consisting of a compound having an amine group and a sulphur atom adapted to react with the polymer base in the vulcanization step. The interaction agent has formula (II) or (III); wherein: y ranges from 0 to 6 R3 is an aliphatic chain containing sulphur and composed of a number of carbon atoms ranging from 1 to 10; wherein: p ranges from 1 to 6.
