SYNTHESIS OF SOME GRAFT POLYMERS OF URACIL

In the reported experiments, poly-6-(acryloloxymethyl)uracil was prepared by radical-catalyzed polymerization of monomeric 6-(acryloyloxymethyl)uracil. The reaction of 6-chloromethyluracil with the potassium salt of polyacrylic acids of molecular weights 5,000 and 90,000 gave polymers with both carboxylate groups and 50-70% pendant uracils. Some inference concerning the arrangement of uracil groups are drawn from the nuclear magnetic resonance (NMR) spectra of the latter polymers. No interaction between poly(A) and the synthetic polymers could be observed.
