ABSTRACT:
The products of the invention are vinyl end-capped oligomers which are prepared from 2,4-bis (p-aminobenzyl) aniline and a vinyl substituted aromatic monoamine, the principal component of which is the compound whose structure is shown in FIG. 3. The products are prepared from either of two (2) precursors. The first precursor is a compound whose structure is shown in FIG. 2 and which is prepared from 2,4-bis (p-aminobenzyl) aniline, a dianhydride of an aromatic tetracarboxylic acid such as 3,3'4,4'-benzophenonetetracarboxylic acid (BTDA) and a vinyl substituted aromatic monoamine, such as 3-aminophenyl-ethylene (APE). The second precursor is a complex amine salt having the structure shown in FIG. 6 and which is prepared from 2,4-bis-(p-aminobenzyl) aniline, a dialkyl ester of BTDA and APE.
