Polyimide and polyisoimide oligomers and precursors thereof, wherein said polymerizable oligomer is end-capped with a diaryl substituted acetylen (DASA) having the general formula:
wherein m = 0 to 5, L=O to 4, R and R¹ are independently selected from the group consisting of halogen (such as fluorine), C₁-C₄ alkyl, alkoxy, aryloxy, haloaryl, haloalkyl, haloacyl, and aryl, acyl, and X is a linking group to the oligomer backbone selected from the group consisting of NH₂, CHO, isocyanate, anhydride, carboxylic acid, ester, acyl halides;
The polyimide or polyisoimide oligomers are useful for composites, molding compounds, adhesives, and electronic applications.
