poly(ethyl acrylate-co-methyl methacrylate-co-triammonioethyl methacrylate chloride)

This is a specialty acrylic copolymer containing ionizable quaternary ammonium groups along with soft acrylate and harder methacrylate segments. The embedded positive charges make it an antimicrobial and antifouling polymer, positioning it as a research-level material rather than a commodity plastic—particularly valuable in biomedical and water-treatment applications where traditional coatings fail to prevent bacterial adhesion and biofilm formation.
