ABSTRACT:
Dense star polyamines having terminal group densities greater than extended conventional star polyamines exhibit greater and more uniform reactivity than their corresponding extended conventional star polyamines. For example, a second generation, amine-terminated polyamine dense star polyamine prepared from tri(2-aminoethyl)amine and aziridine has 4.7.times.10.sup.-3 amine moieties per unit volume (cubic Angstrom units) in contrast to the 1.7.times.10.sup.-3 amine moieties per unit volume contained by an extended conventional star polyamine. Such dense star polyamines are useful as calibration standards, high efficiency proton scavengers and in making size selective membranes.
