Poly(acrylic acid) (PAA; trade name Carbomer) is a synthetic high-molecular weight polymer of acrylic acid. The IUPAC name is poly(1-carboxyethylene). They may be homopolymers of acrylic acid, or crosslinked with an allyl ether of pentaerythritol, allyl ether of sucrose, or allyl ether of propylene. In a water solution at neutral pH, PAA is an anionic polymer, i.e. many of the side chains of PAA will lose their protons and acquire a negative charge. This makes PAAs polyelectrolytes, with the ability to absorb and retain water and swell to many times their original volume.
