The reaction of polyuridylic acid with sodium bisulfite produces modified polymers in which up to 95% of the uracil residues have been converted to uracil-6-sulfonate residues. A 91.6% bisulfite-saturated polymer was found to resist hydrolysis by spleen phosphodiesterase and phosphorolysis by polynu
