The investigation of adhesion promoters prepared by the reaction of amino-functional silanes with dianhydrides (or diester-diacid chlorides) of tetracarboxylic aromatic acids is reported. The new coupling agents, designed to exhibit superior thermo-oxidative stability were applied under conditions determined from kinetic studies of hydrolysis and condensation reactions, and their coupling effectiveness for polyimides was evaluated by peel tests. For a wholly aromatic imide silane (CA-25), adhesion retention after prolonged exposure to elevated temperature was far greater than obtained with adhesion promoters previously evaluated in polyimide systems.
