Abstract
The variation of the elastic constant of an oriented C6H6 monocrystal shows the occ urenre of an irreversible process above 20 GPa. This process leads to the format ion of a polymer- as it was shown by IR study. The bulk modulus of the recovered product is one order of magni t ude above that of solid benzene, this gives ev idence for a reconstruct ion of the bonds in the sample. La mesure de constantes élastiques réalisée sur un monocristal orienté de benzene montre qu' un processus irréversible se développe au-delá de 20 GPa. La formation d'un Polymére Peut ětre constatée aprés I'exdpérience. Le module de rigidité du produit formé, un ordre de grandeur au-dessus de Celui du benzene solide, montre clairement qu'une reconstruction des liaisons a eu lieu.Keywords
