An Alcogel Based on Poly(2-acrylamido-2-methylpropane sulphonic acid) and the Effect of Neutralization Degree on its Swelling, Thermal and Mechanical Properties

An Alcogel Based on Poly(2-acrylamido-2-methylpropane sulphonic acid) and the Effect of Neutralization Degree on its Swelling, Thermal and Mechanical Properties

Cross-linked polymeric organogels have attracted much attention in recent years. Most synthesized organogels are based on low molecular weight or denderitic materials. The study focuses on the preparation of an alcohol absorbent organogel based on 2-acrylamido-2-methylpropane sulphonic acid (AMPS) t...

The study focuses on the preparation of an alcohol absorbent organogel based on 2-acrylamido-2-methylpropane sulphonic acid (AMPS) through cross-linking polymerization. Polyethylene glycol diacrylate-400 and ammonium persulphate were used as crosslinker and thermal initiator, respectively. Neutralization of acid groups increases swelling in superabsorbents.
