Summary

Low-temperature polycondensation of 3,5-diaminobenzoic acid (DABA) was carried out with the aid of N,N-diisopropylcarbodiimide (DIC) as carboxyl group activators. Reaction conditions were selected to obtain oligomeric hyperbranched polyamides. The polycondensation was found to proceed according to the simple model of hyperbranched polymerization with the apparent rate constant of reaction between carboxyl and amino groups equal to 8.58 · 10-3 min-1.


Key words: low-temperature polycondensation, non-linear polyamides, hyperbranched oligomers
