| ------2-Acrylamido-2-Methyl Propane Sulfonic Acid ------ |
Abbreviation: AMPS
Molecular formula : C7H13NO4S
Property: 2-Acrylamide-2-methylpropanesulfonic acid is a vinyl monomer with sulfonic acid group, good thermal stability (Decomposition temperature is up to 210 ° C), the Decomposition temperature of its sodium salt homopolymer is up to 329 ° C; its hydrolysis in Aq. Solution is slow,its sodium Aq. solution owns excellent hydrolysis resistance under conditions of high PH value; in acidic condition, the hydrolysis resistance of copolymer is much higher than polyacrylamide. Its monomer can be made into crystal or can also be made into Aq. solution of sodium salt.
