Abstract
By means of a two-component dilution technique we have evaluated a series of primary and tertiary aminosilanes as adhesion promoters for polyimides and native SiO2 in order to study the effect of chain-scission during covalent bond formation between the adhesion promoters and the polyimide. A rapid leveling-off of the increase in adhesion with an increase in the concentration of the reactive component may indicate that the scission of the polymer chains at the interface is detrimental to adhesion. An attempt to use a secondary aminosilane to obtain bonding without scission was unsuccessful. The reaction was not quantitative, as judged by model compounds, and the diamide product decomposed at elevated temperatures yielding a thermally stable imide via chain scission.
