2023/5/19
2-Hydroxyethyl acrylate (2-HEA) is an organic compound that has the formula C5H8O3. It is a colorless liquid that has a mild odor and is soluble in water and organic solvents. It is an ester of acrylic acid and ethylene glycol, containing both an acrylate and a hydroxy group in its molecule. It is a hydroxy functional acrylic monomer that can be used to synthesize polymers with various properties and applications.
2-HEA is obtained by the reaction of ethylene oxide with acrylic acid in the presence of a catalyst. It can also be synthesized from allyl alcohol and acrylic acid in the presence of a catalyst.
2-HEA can be polymerized with other monomers, such as methyl methacrylate, styrene, vinyl acetate, and acrylic acid, to produce homopolymers and copolymers with different characteristics. 2-HEA can also be used as a crosslinking agent or a modifier for other polymers, such as polyurethanes, polyesters, and polyamides. Here are some of the uses and benefits of 2-HEA and its polymers:
2-HEA can also be used to modify epoxy resins with low hydroxy content and high viscosity. These resins can be diluted with 2-HEA to reduce their viscosity and improve their processability. They can also be modified with 2-HEA to increase their flexibility, toughness, impact resistance, and water resistance. These modified resins can be used for applications that require good mechanical properties and durability.
2-HEA can also be used to modify polyurethane adhesives with low hydroxy content and high viscosity . These adhesives can be copolymerized with 2-HEA to increase their hydroxy content and reduce their viscosity . They can also be modified with 2-HEA to improve their adhesion ,compatibility ,and crosslinking density . These modified adhesives can be used for applications that require good performance and reliability .
2-HEA can also be used to modify polyester optical materials with low transparency ,refractive index ,and dispersion .
