2-Acrylamido-2-methylpropanesulfonic acid-acrylic acid copolymer CAS 40623-75-4 ke eng?

Acrylamide-2-methylpropanesulfonic acid copolymer (AA/AMPS) ke polymer e ncha e qhibilihang ka metsing e entsoeng ka copolymerization ea free radical ea acrylic acid (AA) le 2-acrylamido-2-methylpropanesulfonic acid (AMPS) monomers. Sebopeho sa eona sa limolek'hule se na le lihlopha tsa carboxyl (- COOH), amide (- CONH ₂), le sulfonic acid (- SO3H), tse nang le thepa e ntle ea thibelo ea sekala, ho hasana, mocheso le ho hanyetsa letsoai. 2-Acrylamido-2-methylpropanesulfonic acid-acrylic acid copolymer ke thepa ea mantlha ea polymer e sebetsang kalafong ea metsi ea indasteri, ho ntšoa ha oli le khase, lik'hemik'hale tsa letsatsi le letsatsi le masimong a mang.
