USE OF A LIGNIN FOR THE MECHANICAL REINFORCEMENT OF AN ELASTOMER AND ELASTOMER THUS REINFORCED

摘要

The invention provides a use 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 m/g and 5 m/g and preferably between 1 m/g and 2.5 m/g. The invention also provides an elastomer thus reinforced in particular without carbon black.
