<p>DISCLOSED IS A POLYIMIDESILOXANE ADHESIVE MADE BY REACTING IN A SOLUTION OF AN ORGANIC SOLVENT A DIANHYDRIDE SELECTED FROM THE GROUP CONSISTING OF BIPHENYL DIANHYDRIDE AND OXYDIPHTHALIC ANHYDRIDE WITH AN APPROXIMATELY STOICHIOMETRIC AMOUNT OF A DIAMINE. THE DIAMINE IS A MIXTURE OF ABOUT 5 TO ABOUT 30 MOLEOF A SILOXANE-CONTAINING DIAMINE AND ABOUT 70 TO ABOUT 95 MOLEOF A NON-SILOXANE CONTAINING DIAMINE. THE NON-SILOXANE CONTAINING DIAMINE IS A MIXTURE OF ABOUT 10 TO ABOUT 90 MOLE 0.000000E+00ACH OF LEAST TWO OF THE DIAMINES 2, 2-BIS (4[4-AMINOPHENOXY]PHENYL)PROPANE, (ALPHA), (ALPHA'')-BIS (4-AMINOPHENYL)-1-4,DIISOPROPYLBENZENE, 3, 3''-AMINOPHENYLSULFONE, AND 1,3-BIS(3-AMINOPHENOXY)BENZENE. THE ADHESIVE CNA BE MADE INTO ONE, TWO, AND THREE-LAYER TAPES (OR DISPENSED IN OTHER WAYS) WHICH HAVE A HIGH TG AND A RELATIVELY LOW BONDING TEMPERATURE.</p> |
