Synthesis and application of oligomers obtained from oxamic acid

and ethylene carbonate (in English)

Polimery 2009, No 2, 99


DOI: dx.doi.org/10.14314/polimery.2009.099



Summary

The reaction between oxamic acid and ethylene carbonate in the presence of potassium carbonate catalyst was studied. The products were characterized by 1H NMR, IR and MALDI ToF techniques. The hydroxyethoxy derivatives of the acid are remarkably thermally stable due to the presence of oxalamidoester group. They were used as components of thermally stable polyurethane foams.


Key words: amidoacids, ethylene carbonate, hydroxyalkylation, oligomerization, chemical structure, thermal stability, polyurethane foams
