Hydroxyethyl acrylate (HEA) is a key functional acrylic ester monomer with molecular formula C5H8O3 and MW: 116.12. Possessing both -COOCH₂- and -OH functional groups in its molecular structure, it exhibits polymerization reactivity alongside hydrophilicity/reactivity, making it a key intermediate in fine chemicals. Its core value lies in the synergistic effect of these two groups, imparting multiple functional properties such as adhesion, flexibility, and hydrophilicity to downstream products.
