2-Hydroxyethyl Acrylate (HEA), identified by CAS 818-61-1, is a monomer that stands out due to its dual functionality: an acrylate group for polymerization and a hydroxyl group for further modification. This article aims to provide an in-depth look at its chemical synthesis and polymerization characteristics, highlighting why it is such a valuable intermediate. NINGBO INNO PHARMCHEM CO.,LTD. is a trusted source for this high-performance monomer.

The synthesis of HEA typically involves the esterification of acrylic acid with ethylene glycol. This process yields a molecule that is highly reactive in addition polymerization. The presence of the hydroxyl group is crucial for imparting specific properties to the resulting polymers, influencing everything from solubility to the ability to form crosslinks. Understanding these 2-hydroxyethyl acrylate properties is key to unlocking its full potential.

Chemical Synthesis and Purity of HEA

The industrial production of 2-Hydroxyethyl Acrylate generally follows established esterification pathways. Acrylic acid is reacted with ethylene glycol, often in the presence of an acid catalyst. The process requires careful control to maximize yield and purity, and often includes the addition of polymerization inhibitors, such as hydroquinone monomethyl ether (MEHQ), to prevent premature polymerization during storage and transport. NINGBO INNO PHARMCHEM CO.,LTD. ensures that its HEA is supplied with high purity and appropriate inhibition for safe handling.

When considering how to buy 2-hydroxyethyl acrylate, quality and consistency are paramount. Manufacturers rely on the predictable behavior of the monomer, which is guaranteed by strict quality control measures.

Polymerization Behavior and Applications

HEA is a highly versatile monomer in polymerization due to its acrylate group, which readily participates in free-radical polymerization. It can be homopolymerized or, more commonly, copolymerized with a wide range of vinyl monomers such as styrene, vinyl acetate, and other acrylates and methacrylates. This copolymerization allows for fine-tuning the properties of the final polymer, tailoring it for specific applications.

The hydroxyl group in HEA plays a pivotal role:

  • Crosslinking: The hydroxyl groups can react with crosslinking agents, such as isocyanates or melamine resins, to form three-dimensional networks. This enhances the mechanical strength, thermal stability, and chemical resistance of coatings and adhesives. This is fundamental to adhesives with hydroxyethyl acrylate.
  • Hydrophilicity: HEA contributes to the hydrophilic character of polymers, making them suitable for applications requiring water absorption or increased wettability, such as in hydrogels or waterborne coatings.
  • Post-Polymerization Modification: The hydroxyl group can be further derivatized through reactions like esterification or etherification, allowing for the introduction of other functional groups or the creation of more complex polymer architectures.

These characteristics make HEA indispensable for UV curable resins HEA formulations and other advanced material applications.
