types of cationic polyacrylamide hydrolysis in Austria

Hydrolysis of cationic polyacrylamides | Semantic Scholar

In the hydrolysis of C-PAM 1 at 22 C and pH 6, the half-life of the cationic groups was 10 days. At pH 7 the half-life was shorter, 24 h, and at pH 8.5 the reaction was very fast with a half-life of about 0.25 h. The charged groups on C-PAM 2,

Polyacrylamide

Polyacrylamide (abbreviated as PAM) is a polymer with the formula (-CH2CHCONH2-). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for
