  • Nonionic Polyacrylamide Available Top Quality at Best

    Abstract. The hydrolysis of polyamides has been studied in buffered acid solution at 110°C. at an amide concentration of 0.05 M. In the case of polyacrylamide, the reaction was carried out in acetate buffer at different values of the ratio r(acetic acid/sodium acetate).
