property: 2-acrylamido-2-methylpropane sulfonic acid is a kind of vinyl monomer with sulfonic acid group, which has a good thermal stability. the decomposition temperature can be up to 210 and the temperature of sodium salt copolymer can reach 329~c. its hydrolysis is very slow in aqueous solution. sodium salt solution has good anti-hydrolysis performance with high ph value. under acid condition, the hydrolysis-resistant performance of its copolymer is better than that of polyacrylamide. the monomer can be made into crystal or sodium salt solution. packing & storing: packed in net 25kg packing. stored in a cool, dry and well-ventilated area. the storage period is 1 year.
