Claim:
A process for adhesively bonding materials or components, comprising: a. providing polybenzoxazoles (PBOs) of formula (I): where a=0 or 1, b=0–100, c=0–100 and d=0 or 1, where a=d; X, if a and d=0, is: —H, alkyl, alkenyl, cycloalkenyl, aryl, aralkyl, aralkenyl, aralkynyl or heterocycloalkyl each unsubstituted or substituted; X, if a and d=1, is: hydroxy, substituted or unsubstituted alkoxy, alkenoxy, aryloxy, cycloalkenoxy, amino, alkylamino, alkenylamino, arylamino, arylalkenoxy, arylalkylamino; Y 1 to Y 4 independently of one another have the following definition: substituted or unsubstituted aryl, a substituted or unsubstituted polynuclear aromatic hydrocarbon compound, a substituted or unsubstituted fused ring system, or alkyl, alkenyl, alkynyl, aralkyl, aralkenyl, aralkynyl, heterocyclo or cycloalkenyl each unsubstituted or substituted; Z 1 to Z 3 independently of one another have the following definition: aryl, aralkyl, aralkenyl, aralkynyl, heteroaryl, a polynuclear aromatic hydrocarbon compound or a fused ring system each unsubstituted or substituted; b. applying the PBOs to the area or areas of the materials or components to be bonded; c. contacting the areas to be bonded with one another; d. subsequently crosslinking the PBOs; and e. adhesively bonding the materials or components through the cross-linking of step (d).
