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 m2/g and 5 m2/g, and preferably between 1 m2/g and 2.5 m2/g. The invention also provides an elastomer thus reinforced, in particular without carbon black.
