Poly(methacrylic acid) (PMAA) is a polymer made from methacrylic acid (preferred IUPAC name, 2-methylprop-2-enoic acid), which is a carboxylic acid. It is often available as its sodium salt, poly(methacrylic acid) sodium salt. The monomer is a viscous liquid with a pungent odour. The first polymeric form of methacrylic acid was described in 1880 by Engelhorn and Fittig. The use of high purity monomers is required for proper polymerization conditions and therefore it is necessary to remove any inhibitors by extraction (phenolic inhibitors) or via distillation. To prevent inhibition by dissolved oxygen, monomers should be carefully degassed prior to the start of the polymerization.

| - El ácido poli(metacrílico) (PMAA) es un polímero hecho a partir de ácido metacrílico. Es soluble en agua, metanol y disoluciones acuosas alcalinas. A menudo se dispone de él en la forma de sal sódica. Tanto el ácido poliacrílico como el polimetacrílico existen como homopolímeros y son usados extensamente como dispersantes y adhesivos. Ambos tienen un limitado uso como plásticos debido a su solubilidad en agua y a su comportamiento como polielectrolito. Los copolímeros también son usados en aplicaciones especiales. (es)

- Полиметакриловую кислоту получают радикальной полимеризацией метакриловой кислоты в массе, водных растворах или в органических растворителях в присутствии радикальных инициаторов. Чаще всего полимеризацию проводят в кислых водных растворах. (ru)
