2-hydroxyethyl methacrylate(HEMA) bụ monomer polymerization nke organic guzobere site na mmeghachi omume nke ethylene oxide (EO) na methacrylic acid (MMA), nke nwere otu bifunctional n'ime molekul. Hydroxyethyl methacrylate bụ ụdị mmiri na-enweghị agba, nke na-apụta ìhè na nke na-adị mfe. Soluble na nkịtị organic mgbaze. Miscible na mmiri.
