Hydroxypropyl Methacrylate: A Hydroxy Functional Methacrylate Monomer for Polymer Synthesis
2023/5/22
Hydroxypropyl methacrylate (HPMA) is an organic compound that has the formula C7H12O3. 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 methacrylic acid and propylene glycol, containing both a methacrylate and a hydroxy group in its molecule. It is a hydroxy functional methacrylate monomer that can be used to synthesize polymers with various properties and applications.
HPMA is obtained by the reaction of propylene oxide with methacrylic acid in the presence of a base. It can also be synthesized from allyl alcohol and methacrylic acid in the presence of a catalyst.
HPMA can be polymerized with other monomers, such as methyl methacrylate, styrene, vinyl acetate, and acrylic acid, to produce homopolymers and copolymers with different characteristics. HPMA 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 HPMA and its polymers:
HPMA can also be used to modify epoxy resins with low hydroxy content and high viscosity . These resins can be diluted with HPMA to reduce their viscosity and improve their processability . They can also be modified with HPMA 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 .
HPMA can also be used to prepare unsaturated polyesters and vinyl esters with high hydroxy content and low viscosity . These esters can be cured by UV light or heat to form crosslinked networks with high strength ,hardness ,adhesion ,chemical resistance ,and thermal stability . These networks can be used for various purposes ,such as photopolymer printing plates ,anchor bolts ,and chemical anchors .
HPMA can also be used to prepare sealants with high hydroxy content and low viscosity . These sealants can be cured by UV light or heat to form crosslinked networks with high elasticity ,adhesion ,compatibility ,and bioactivity . These networks can be used for various purposes ,such as vacuum impregnation of cast aluminum components .
Conclusion
HPMA is a versatile chemical compound that has various uses and benefits for coatings ,reactive resins ,adhesives ,acrylic polyols ,unsaturated polyesters ,vinyl esters ,polyacrylamide gels ,and sealants . It is a hydroxy functional methacrylate monomer that can synthesize polymers with different characteristics and applications . HPMA is widely available and affordable ,and can be used for various purposes . However ,it should be handled with care and under proper conditions ,as it may cause irritation or sensitization .
