Abstract

Des liquides électrovisqueux homogènes contiennent des savons d'aluminium ou sont constitués de tels savons d'aluminium, ces savons d'aluminium étant obtenus à partir des produits de la réaction d'un ou plusieurs acides polycarboxyliques ou de leurs anhydrides ou semi-esters avec des composés réactifs d'aluminium. Ces liquides ont un effet électro-rhéologique important et sont totalement homogènes.
