ABSTRACT:
The Si-modified bis-phthalic acid derivatives according to the invention are monomeric, oligomeric or polymeric compounds. An example of a monomeric compound of the invention is the amidoacid of the formula ##STR1## which is formed by reacting 4,4'-diaminodiphenylmethane and 4-N,N'-bis-[3-tri-n-propoxy)-silyl-propyl]-aminophthalic anhydride in solution, in a molar ratio of 1:2. To produce oligomeric or polymeric compounds, the reaction has to be carried out with a 3rd component, for example pyromellitic dianhydride.
The products are used as adhesion promoters, for example between inorganic solids and organic resins.
