Reinforced rubber composition based on, exhibiting a lesser hysteresis degradation over time, based on at least (a) an elastomeric matrix predominantly based on natural rubber, (b) a reinforcing filler and (c) a specific polyimine compound in a content of between 6 and 20 mmol per 100 g of elastomer. This rubber composition is intended, for example, for the manufacture of a semi-finished rubber product intended for the tyres of motor vehicles.
