- Are hydrophobically modified polyacrylamides hydrolyzed?
- In this work, a series of hydrophobically modified polyacrylamides and their hydrolyzed derivatives have been prepared via micellar polymerization at high monomer concentration (19 wt%) and post-hydrolysis. 1 H and 13 C NMR elucidation of polymer microstructures displayed a good agreement with feed ratio.
- What are hydrophobically associating polyacrylamides (hapams)?
- Of particular interest in this class are hydrophobically associating polyacrylamides (HAPAMs), derived from polyacrylamide by introducing a relatively low amount (generally less than 2 mol%) of hydrophobic pendent groups .
- How does salt affect hydrophobic modified polyacrylamide?
- In the presence of salt, the “classical” behaviour of hydrophobic modified polyacrylamide in dilute regime is recovered: the chain collapses due to intramolecular hydrophobic association when the strength of hydrophobic interactions is reinforced by the “salting out” effect.
- How is acrylamide polymerized?
- A given amount (0.25 mol, 17.77 g) of acrylamide was dissolved in 500 ml water followed by 30 min purified nitrogen purge. 2.5 ml of 0.1 mol l −1 KPS and TMEDA aqueous solutions were then injected successively. The polymerization was conducted at 30.0±0.1 °C with a thermostatically controlled water circulating bath.
