Abstract: A PROCESS FOR THE PREPARATION OF A MICROPOROUS CELLULAR POLYIMIDE ARTICLE COMPRISING PREPARING A MIXTURE IN AN INERT SOLVENT OF POLYAMIC ACID AND P,P''-OXYBIS(BENZENE SULFONYL HYDRAZIDE) AS A BLOWING AGENT, FORMING THE MIXTURE INTO A SHAPED ARTICLE, ALLOWING THE ARTICLE TO DRY WHEREIN THE BLOWING AGENT SIMULTANEOUSLY DECOMPOSES TO FORM A FOAMED ARTICLE AND HEATING THE FOAMED ARTICLE TO CYCLIZE THE POLYAMIC ACID IS DISCLOSED. THE FOAMED ARTICLE

CONTAINS MICROPORES OF ABOUT 1 MICRON IN DIAMETER WHICH IMPROVES ADHESION AT POLYMER-POLYMER AND POLYMERMETAL INTERFACES.
