Toxicity of Anionic Polyacrylamide Formulations when Used for Erosion Control in Agriculture
Addition of anionic polyacrylamide (PAM) to agricultural irrigation water can dramatically reduce erosion of soils. However, the toxicity of PAM to aquatic life, while often claimed to be low, has
Another low volume but important use of anionic and cationic polyacrylamides is gel electrophoresis for macromolecule separation. When an electic field is applied across a PAM gel, the (negatively) charged proteins or nucleic acids migrate

Polyacrylamide Emulsions Handbook 3 z Dewatered emulsions For dewatered emulsions, the situation is different. They are not concerned by raincycle. Asthe content of water is very low there is no formation of skins and lumps during freezing or
Anionic polyacrylamides are easier to polymerize to very high molecular weights. We produce anionic powder flocculants / polyacrylamides (ADPAM) with anionic charge density ranging from 0-100%. We also offer anionic inverse emulsion (AEPAM)

Glyoxalated Polyacrylamides G-PAM: additives for enhancing the strength of paper. Giovanna Pellegrini RQ, Axchem® Italia -Stéphan Lafrenière
Summary: Glyoxalated polyacrylamides (G- PAM) provide an alternative chemistry to other papermaking resins additives for wet and dry strength. This new generation of G-PAM provides a better compromise between wet end chemistry performance and
