Technical Abstract: Novel oligomeric prepolymers were synthesized by acid-catalyzed condensation of glycerol with iminodiacetic, azelaic, or succinic acid. The prepolymers were obtained, on average, in 62% yield and were characterized by 13C NMR, 1H NMR, MALDI-TOF mass spectrometry, and GPC. The synthesized oligomers had an average molecular weight of 1543 daltons (average PDI=1.34, average DOP= 5.5). Hyperbranching was evident in the products that employed azelaic acid and succinic acid as co-monomers with glycerol whereas the reaction between iminodiacetic acid and glycerol resulted in linear products bearing cyclic urethanes.
