Mono(2-acryloyloxyethyl) Succinate (stabilized with MEHQ) TCI M1824

TCI M1824 Mono(2-acryloyloxyethyl) Succinate is a difunctional acrylate monomer that carries a polymerizable acrylate group at one end and a free carboxylic acid group at the other, linked through a succinate and ethylene glycol bridge. The product is stabilized with MEHQ to prevent premature polymerization during storage and shipping. In materials and polymer laboratories, a monomer of this kind serves as a functional comonomer that inserts acid groups into the polymer chain, so that the surface properties, polarity, and adhesion of the finished product can be tuned in a deliberate, directed way.

The characteristic that makes it a preferred choice is the presence of a free carboxylic acid group that does not take part in the reaction while radical polymerization proceeds. That acid group improves adhesion to polar surfaces such as metal, glass, and mineral substrates, improves compatibility with water-based systems, and provides an attachment point for further reactions, for example salt formation, amidation, or ionic crosslinking. The acrylate group, meanwhile, delivers a rapid polymerization rate under radical initiation as well as under ultraviolet irradiation. Its physical form, generally a viscous liquid, allows it to be blended into formulations without an additional dissolution step.

In Indonesian laboratories, this monomer is typically used in university and institutional research groups working on coatings, adhesives, dental and biomedical materials, and functional polymer synthesis. It is normally handled in small quantities on a bench scale, weighed into formulation batches alongside other acrylate monomers and a radical or photoinitiator system. Because it is supplied in research pack sizes, it suits method development and trial formulation work rather than production-scale use.

• Functional comonomer in radical copolymerization, where its free carboxylic acid group is carried into the polymer backbone to raise chain polarity and introduce acid functionality for later modification.
• UV-curable coating formulation, because the acrylate group polymerizes rapidly under ultraviolet irradiation while the pendant acid group improves wetting and anchoring on metal and glass substrates.
• Adhesive and primer research, where the free carboxylic acid provides strong interaction with polar mineral and metallic surfaces and therefore improves bond strength of the cured acrylate network.
• Water-compatible and waterborne polymer systems, since the acid group can be neutralized to a salt form and so improves dispersion and compatibility of the resin in aqueous media.
• Preparation of ionically crosslinked or post-functionalized polymers, using the unreacted carboxylic acid as an attachment point for amidation, esterification, or ionic crosslinking after the acrylate chain has formed.

Store the container in a cool, dark place, kept closed and protected from direct sunlight and from sources of heat, since acrylate monomers can polymerize prematurely when warmed or exposed to light. Keep the material in its original tightly sealed container, or in a chemically compatible closed container, and do not remove or deplete the MEHQ stabilizer, as the inhibitor requires the presence of air to remain effective. Handle in a well-ventilated area or fume hood, wearing gloves, safety glasses, and a laboratory coat, because acrylate monomers are skin and eye irritants and may cause sensitization on repeated contact. Avoid contact with radical sources, strong oxidizing agents, and peroxides. Withdraw only the quantity required for the experiment and avoid returning unused material to the original container.
