Hydroxypropyl methacrylate, mixture of isomers, ≥ 95%, is a hydrophilic methacrylate monomer used in polymer synthesis, coatings, adhesives, hydrogels, and UV-curable formulation research. Its methacrylate functionality supports free-radical polymerization, while the hydroxypropyl group can contribute hydrophilicity, adhesion, flexibility, and compatibility in polymer networks.
Synonyms and related names: HPMA; methacrylic acid hydroxypropyl ester; propylene glycol monomethacrylate.
This inhibited monomer is commonly evaluated in acrylic and methacrylate systems where water interaction, crosslinking behavior, adhesion, coating performance, or resin formulation properties are important. It may be used in research involving hydrogel networks, specialty coatings, adhesive systems, dental materials research, and photopolymer formulations.
Final suitability should be confirmed under the user’s specific formulation, polymerization method, processing conditions, and end-use requirements.

Applications
Hydrogels & Biomedical Materials Research
Hydroxypropyl methacrylate may be used in hydrogel and biomedical materials research where hydrophilicity, polymer network formation, and water interaction are important design considerations.
Coatings & Adhesives
HPMA can be evaluated in coating and adhesive formulations to modify adhesion, flexibility, polarity, and compatibility within acrylic or methacrylate-based systems.
UV-Curable & Photopolymer Resins
The monomer may be used in photopolymer and UV-curable resin research where reactive methacrylate functionality is needed for polymerization or crosslinking studies.
Dental Materials Research
HPMA may be evaluated in dental materials research and methacrylate resin systems where formulation compatibility, mechanical properties, and polymer network behavior are being studied.
Polymer Synthesis & Modification
This monomer is useful for preparing acrylic copolymers and functional methacrylate polymers with increased hydrophilicity or hydroxy-functional character.
Formulation & Polymerization Considerations
- Contains inhibitor to support storage stability
- Polymerization behavior depends on initiator, inhibitor level, oxygen exposure, temperature, light exposure, and formulation composition
- Hydrophilicity and compatibility depend on comonomers, crosslinkers, solvent system, and polymerization conditions
- Evaluate resin performance, cure behavior, and final polymer properties under intended conditions
HPMA formulation performance can vary with monomer ratio, inhibitor removal or retention, initiator package, curing method, and processing environment.
Preparation Tips
- Mix thoroughly before use if required by the application
- Use clean, dry, compatible glassware and formulation equipment
- Protect formulations from unintended heat, light, or initiator exposure
- Account for inhibitor content when developing polymerization or curing conditions
- Perform small-scale compatibility and cure testing before preparing larger batches
- Confirm lot-specific values with the Certificate of Analysis when required
Handling & Storage
- Store at room temperature
- Keep container tightly closed when not in use
- Use appropriate ventilation
- Wear gloves and chemical goggles
- Avoid skin and eye contact
- Handle as an irritant chemical
- Review the Safety Data Sheet before use

1. What is Hydroxypropyl methacrylate used for?
Hydroxypropyl methacrylate is used in polymer synthesis, hydrogels, coatings, adhesives, UV-curable resin research, dental materials research, and functional acrylic or methacrylate polymer formulations.
2. What does “mixture of isomers” mean?
It means the product contains hydroxypropyl methacrylate isomers rather than a single isolated isomer. Formulation performance should be evaluated under the intended polymerization and processing conditions.
3. Is this product inhibited?
Yes. The product listing identifies approximately 200 ppm MEHQ inhibitor.
4. Can HPMA be used in UV-curable systems?
HPMA may be used in UV-curable and photopolymer resin research when paired with suitable initiators, comonomers, and curing conditions.
5. How should this product be stored and handled?
Store at room temperature with the container tightly closed. Handle with appropriate ventilation, gloves, and chemical goggles, and review the SDS before use.
Safety & Documentation
Review the product specification and Safety Data Sheet before use. Hydroxypropyl methacrylate is listed as an irritant and should be handled with appropriate ventilation, gloves, chemical goggles, and standard laboratory chemical handling practices. Confirm lot-specific test results with the Certificate of Analysis when required.
