Plastic containing mixtures containing 0.1 - 30% by weight, calculated on the total weight of the mixture, of a substance improving the internal adhesion between the phase boundaries of the heterogeneous system, which substance is selected among aromatic mono-, di-, tri-, and tetracarboxylic acids, and their anhydrides and esters, which are solids with a melting point in excess of 30`C. By adding such substances, the property profile of the plastic containing mixtures is improved, which mixtures apart from one or more plastics also can contain one or more fillers or reinforcing agents. Melanges contenant des matieres plastiques comprenant, en poids, 0,1 a 30%, par rapport au poids total du melange, d'une substance ameliorant l'adhesion interne entre les limites des phases du systeme heterogene, cette substance etant choisie parmi les acides aromatiques mono, di, tri, et tetracarboxyliques, leurs anhydrides et esters, qui sont solides et ont un point de fusion superieur a 30 C. L'addition de ces substances permet d'ameliorer les proprietes des melanges contenant une matiere plastique, ces melanges pouvant egalement contenir une ou plusieurs substances de remplissage ou des agents de renforcement.
