"The water absorbency of the anionically starch-grafted AA/AM absorbent is markedly affected by the pH of the buffer solution at different ionic strengths. The charge of the ionic monomer affects the pH sensitivity of the superabsorbent polymers. An acidic superabsorbent normally ionizes at high pH but unionizes at low pH."

Etymology
From poly- + -mer, from Ancient Greek πολύς (polús, “many”) + μέρος (méros, “part”). Coined by Jöns Jacob Berzelius in 1833, though his definition was quite different from the modern one.
