Cationic polyacrylamide copolymers (PAMs): environmental half

Cationic polyacrylamide copolymers (PAMs) are a group of water-soluble polymers with a wide range of applications in industry, food processing, agriculture and waste management. One of the major applications for PAM is sludge dewatering in municipal waste water treatment plants (MWWTPs).

polyacrylamide - wikipedia

Polyacrylamide - Wikipedia

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). 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 water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

Synthesis of block cationic polyacrylamide precursors using

Synthesis of cationic polyacrylamides (CPAMs) by introducing cationic polymer precursors followed by chain extension of acrylamide (AM) homopolymer blocks via RAFT polymerization is a promising approach for engineering high-performance CPAMs.

These values depend largely on the solution pH. The adsorbed amounts of cationic PAM increase with the pH decrease (higher adsorption of CT PAM is observed at pH 7 than 5). The pK b value for the cationic polyacrylamide is 9.3. At pH 5 and 7 the degree of quaternary amine groups dissociation in the polymer chains varies in the range of 99.4

In this work, instead of the ¡°grafting from¡± route, we successfully applied the ¡°grafting to¡± strategy in the synthesis of high performance lignin-grafted cationic PAM flocculant. At first, a linear cationic polyacrylamide (CPA) prepolymer terminated with chlorine was synthesized via normal free radical polymerization.
