Polyacrylamide - an overview | ScienceDirect Topics
Polyacrylamide (PAM) is a commercially relevant cationic polymer utilized mainly for water treatment due to its high efficiency and rapid dissolution. Being a cationic polymer, PAM can increase the settling rate of bacterial floc and improve the
The term “polyacrylamide” is loosely used to describe any polymer with acrylamide present as one of the monomers. 1 More rigorously, its IUPAC nomenclature is poly (prop-2-enamide), which
Cationic polymerization
Monomers Monomer scope for cationic polymerization is limited to two main types: alkene and heterocyclic monomers. Cationic polymerization of both types of monomers occurs only if the overall reaction is thermally favorable. In the case of
The MW of the copolymers prepared using emulsion polymerization (10 7-10 9 Da) was generally larger than that of copolymers prepared using solution polymerization (4×10 7-10 8 Da). When the amount of cationic monomer was increased from 10 to
