AbstractPoly(alkylene phosphate)s bearing regularly distributed uracil moiety in the main chain have been obtained. The synthetic procedure consists of condensation of bis(diethylamino)‐methoxyphosphine withN1,N3‐bis(2′‐hydroxyethyl) uracil followed by oxidation, dealkylation, and transformation to the resulting sodium polysalt. The final polymer (\documentclass{article}\pagestyle{empty}\begin{document}$\bar M_n \approx 10^4 $\end{document}) as well as the intermediate products were characterized by1H‐,13C‐, and31P‐NMR
