Polyacrylamide degradation and its implications in environmental

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

Preparation and properties of cationic polyacrylamide

Polyacrylamides (PAM) are an important class of water-soluble polymers with low synthetic cost, high viscosity, and good rheological properties. PAM is widely used for oil and gas extraction and wastewater treatment industries, especially in drilling fluids, fracturing fluids, polymer drives and other oil and gas extraction fields.

Water Soluble Polymer Flocculants: Synthesis, Characterization,

The reduction in the negative zeta potential was found to be considerably greater in the presence of cationic polyacrylamide than anionic and amphoteric polyacrylamide, due to an increased adsorbed layer thickness of cationic polyacrylamide. 208 Amphoteric polymers exhibit both cationic and anionic behaviors, and their strength and a relative number of sites vary depending on surface charge

Synthesis and evaluation of cationic polyacrylamide

This study addresses the challenge of microalgae harvesting through the development of flocculants. Two positively charged cationic polymers including poly[2 (acryloyloxy)ethyl]trimethylammonium chloride (PAETAC) and poly(3 acrylamidopropyl)trimethylammonium chloride (PAmPTAC) were synthesized using the UV-induced radical polymerization, for harvesting both freshwater and marine microalgae.

Thermal decomposition behavior and mechanism study of cationic

Abstract The thermal decomposition behavior of polyacrylamide poly (methacryloyloxyethyl trimethylammonium chloride-acrylamide) (P (DMC-AM)) was studied by means of TG and DSC under nitrogen atmosphere at temperature range of 323.15¨C823.15 K. The effect of cationicity on thermal stability was discussed.
