Polyacrylamide degradation and its implications in environmental

The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1, 9,...

Water Soluble Polymer Flocculants: Synthesis, Characterization, and

For the sake of our discussion, we chose to classify flocculants in three major categories: i) synthetic flocculants, ii) natural/bio flocculants, with a separate category dedicated to iii) stimuli-responsive flocculants.

Fabricating an anionic polyacrylamide (APAM) with an anionic block

Flocculation experimental results demonstrated that the anionic microblocks in the template copolymer could enhance the charge neutralization and bridging ability, and therefore an excellent flocculation performance of treating high turbidity water was observed. 1. Introduction

A method for measuring the degree of anionicity of polyacrylamide-based

Anionicity 1. Introduction The majority of flocculants employed in mineral processing are polyacrylamide-based high molecular weight polymers. Polyacrylamide (PAM) is nominally a nonionic uncharged polymer. However, industrial polyacrylamides are in fact partially hydrolyzed to yield a number of acrylic units along the main macromolecule chain.

Anionic polyacrylamides make up the largest portion of the polyacrylamide market. The polymers can be prepared over a wide range of anionic charges and molecular weights (1000 to > 20,000,000 molecular weight). The workhorse comonomer for the production of anionic polyacrylamides is acrylate salts of acrylic acid.
