摘要：

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 H-1 NMR spectroscopy. The oligomers obtained have higher thermal stability in comparison with their analogues obtained from aliphatic diols.
