RAPID COMMUNICATION
Urethane oligomers with pyrimidine rings (in English)

Polimery 2008, No 10, 760


DOI: dx.doi.org/10.14314/polimery.2008.760

Summary

New urethane oligomers containing pyrimidine rings were obtained from N,N'-bis(hydroxymethyl)barbiturate and bifunctional isocyanates. The products were isolated and identified on the basis of elemental analysis, IR and 1H NMR spectroscopy. The oligomers obtained have higher thermal stability in comparison with their analogues obtained from aliphatic diols.


Key words: N,N'-bis(hydroxymethyl)barbiturate, isocyanates, polyaddition, urethane oligomers, thermal stability
