Poly(acrylic acid) (PAA or Carbomer) is generic name for synthetic high molecular weight polymers of acrylic acid. They may be homopolymers of acrylic acid crosslinked with an allyl ether 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.
