Diethylene glycol dimethacrylate (DEGDMA) is a difunctional methacrylate monomer used to introduce crosslinking or branching sites into compatible polymer systems. Its diethylene glycol spacer provides hydrophilic character, making DEGDMA useful for research involving crosslinked polymer networks where increased polarity is desired.
Product 02214 is a colorless to light-yellow, clear liquid with a minimum GC purity of 88%. It contains 400–600 ppm MEHQ inhibitor.
DEGDMA can be used in polymer synthesis and compatible coatings, inks, adhesives, and other curable formulations. Final cure response and material properties depend on the complete formulation, monomer concentration, initiator system, and processing conditions.

Applications
Crosslinked Polymer Synthesis
DEGDMA provides two polymerizable methacrylate groups that can introduce crosslinking or branching sites into compatible polymer architectures. It is useful for studying how crosslinker concentration affects network formation and resulting material properties.
Hydrophilic Polymer Networks
The diethylene glycol spacer gives DEGDMA hydrophilic character. This makes it useful in crosslinked polymer research where polarity or interaction with aqueous environments is important. Water compatibility and swelling behavior should be confirmed in the complete polymer system.
Coatings, Inks, and Adhesive Formulations
DEGDMA can function as a difunctional crosslinking component in compatible methacrylate-based coatings, inks, adhesives, and related curable formulations. Performance should be established experimentally for the intended formulation and process.
Formulation Considerations
Because DEGDMA is difunctional, its concentration can affect crosslink density and the properties of the resulting polymer network.
- Account for the product’s 400–600 ppm MEHQ inhibitor when developing polymerization or cure conditions.
- Confirm compatibility with the selected comonomers, initiator system, additives, and processing method.
- Determine the appropriate concentration through application-specific testing.

What is diethylene glycol dimethacrylate used for?
Diethylene glycol dimethacrylate is a difunctional methacrylate monomer used to introduce crosslinking or branching sites into compatible polymer systems. It can be used in polymer synthesis and compatible coatings, inks, adhesives, and other curable formulations.
What does DEGDMA stand for?
DEGDMA stands for diethylene glycol dimethacrylate. Product 02214 has CAS number 2358-84-1 and a minimum GC purity of 88%.
Is DEGDMA the same as EGDMA, TEGDMA, or DEGDA?
No. DEGDMA is diethylene glycol dimethacrylate. EGDMA is ethylene glycol dimethacrylate, TEGDMA is triethylene glycol dimethacrylate, and DEGDA is diethylene glycol diacrylate. These materials differ in glycol spacer length, polymerizable end groups, or both, and should not be treated as interchangeable without formulation testing.
Is DEGDMA a hydrophilic crosslinking monomer?
Yes. DEGDMA combines two polymerizable methacrylate groups with a hydrophilic diethylene glycol spacer. Its behavior in water or an aqueous formulation depends on the complete polymer system and degree of polymerization.
What should be considered when polymerizing DEGDMA?
DEGDMA contains 400–600 ppm MEHQ inhibitor. Consider the inhibitor level, crosslinker concentration, comonomer compatibility, initiator system, temperature, and other processing conditions when developing a polymerization or cure process.
