• It is produced industrially mainly as a precursor to polyacrylamides, which find many uses as water-soluble thickeners and flocculation agents.
• Because of their ability to absorb several hundred times their own weight in water, polyacrylamides and polymethacrylates (also known as hydroabsorbent polymers, superabsorbent polymers or hydrogels) were tested in agriculture, horticulture and landscaping beginning in the 1960s.
• Long-chain polymer flocculants, such as modified polyacrylamides, are manufactured and sold by flocculant producers.
• ASA emulsions are prepared like AKD dispersions with polycations as protective colloids and retention aids (especially with cationic starch or cationic polyacrylamides (C-PAM) in the ratio ASA to cation of about 2: 1) and with about 1% anionic or nonionic surfactants.
