Abstract
By the method of one-stage high-temperature polycondensation of 1,4-phenylene-bis-(5-oxy-1,3-phenylenediamine) (B4 monomer) with 4-(3-aminophenoxy)phthalic acid (AB monomer) in molten benzoic acid, four-arm star-shaped oligoimides with terminal amino groups were synthesized. Oligomers have a narrow molecular weight distribution (D = 1.2–1.3) and are soluble in organic solvents. The star-shaped oligoimides with terminal acetamide fragments were obtained by acylation of terminal amino groups with acetic anhydride.
