Ethyl acrylate is an organic compound with the chemical formula C5H8O2, appearing as a colorless liquid. It is slightly soluble in water and ethanol. It readily polymerizes and can also copolymerize with other monomers. It is used in the preparation of polymers such as plastics and resins, and can also serve as an intermediate in organic synthesis.

It is primarily used as a comonomer for synthetic resins, and the resulting copolymers are widely applied in industries such as coatings, textiles, leather, and adhesives. It is employed in the synthesis of plastics and resins. Ethyl acrylate is an intermediate in the production of the carbamate insecticide benfuracarb. It can also be used as a raw material for protective coatings, adhesives, and paper impregnating agents. Its polymers can act as anti-cracking agents for leather. Its copolymer with ethylene serves as a hot-melt adhesive, and its copolymer with 5% chloroethyl vinyl ether is a synthetic rubber with excellent oil and heat resistance.
