Hydroxypropyl Acrylate: A Difunctional Acrylate Monomer for Polymer Synthesis
2023/5/22
Hydroxypropyl acrylate (HPA) is an organic compound that has the formula C6H10O3. It is a colorless liquid that has a mild odor and is miscible with water and soluble in most organic solvents. It is an ester of acrylic acid and propylene glycol, containing both an acrylate and a hydroxy group in its molecule. It is a difunctional acrylate monomer that can be used to synthesize polymers with various properties and applications.
HPA is obtained by the reaction of propylene oxide with acrylic acid in the presence of a base. It can also be synthesized from allyl alcohol and acrylic acid in the presence of a catalyst.
HPA can be polymerized with other monomers, such as methyl methacrylate, styrene, vinyl acetate, and acrylic acid, to produce homopolymers and copolymers with different characteristics. HPA can also be used as a crosslinking agent or a modifier for other polymers, such as polyolefins, polyesters, and polyamides. Here are some of the uses and benefits of HPA and its polymers:
HPA can also be used to modify epoxy resins with low hydroxy content and high viscosity. These resins can be diluted with HPA to reduce their viscosity and improve their processability. They can also be modified with HPA 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.
HPA can also be used to modify polyurethane foams and elastomers with low hydroxy content and high viscosity . These foams and elastomers can be copolymerized with HPA to increase their hydroxy content and reduce their viscosity . They can also be modified with HPA to improve their mechanical properties ,adhesion ,compatibility ,and bioactivity .
