METHOD FOR DETERMINING THE COMPOSITION OF AMPHOTERIC CRYOGELS BASED ON SYNTHETIC MONOMERS

Abstract

The author proposed a simple method for determining the composition of amphoteric cryogels based on the method of potentiometric titration. Complex equipment and highly qualified employees are not required to perform the analysis. The proposed method has shown effectiveness on the example of a copolymer of methacrylic acid and dimethylaminoethylmethacrylate. The ratio of acidic and basic groups in the structure of cryogels based on crosslinked copolymers with different degrees of crosslinking has been established.
