2-Acrylamido-2-Methylpropane Sulfonic Acid
AMPS
|
CAS No.: 15214-89-8
|
Molecular Formula: C7H13NO4S
|
|
Synonyms: 2-acrylamido-2-methylpropanesulfonate |
Molecular Weight: 207.24 |
Properties&Usage:
AMPS shows good complexation, adsorbability, bioactivity, surfactivity, stability against hydrolysis and heat due to the sulphonic group, amide group and unsaturated bond. The hydrolyzing rate of monomer AMPS in the water is very slow and it show better anti-hydrolysis than the PAM. AMPS has been widely used in water treatment, oilfield, synthetic fiber, textile auxiliary, paper making, etc.
