Abstract

A method for the mechanical reinforcement of elastomer polymers, of a chemically unmodified lignin with available functional groups which has a specific surface area of between 0.5 m2/g and 5 m2/g, and preferably between 1 m2/g and 2.5 m2/g. Also an elastomer thus reinforced, in particular without carbon black.
