General description

2-Hydroxyethyl acrylate (HEA) is a monomer that is widely used in the field of material synthesis for the production of various types of polymers, such as hydrogels, coatings, adhesives, and thermosets. Its versatility lies in its ability to copolymerize with a variety of monomers, resulting in a wide range of polymer properties and applications. Its main use is in the production of hydrogels, which are highly absorbent and can be used in wound dressings, contact lenses, drug delivery systems, and other biomedical applications. Additionally, 2-hydroxyethyl acrylate-based coatings and adhesives are used in various surface modification and bonding applications, owing to their excellent adhesion, flexibility, and chemical resistance properties.

Application

Porous hydrogels can be prepared by copolymerization of 2-hydroxyethyl acrylate and a cross linking agent. 2-hydroxyethyl acrylate may be used in the synthesis of amphilic block copolymers by nitroxide mediated living radical polymeration. Also, it may be used to prepare tuned poly(hydroxyethyl acrylate) by atom transfer radical polymerization.

Poly(2-hydroxyethyl acrylate) (PHEA) is an interesting biomaterial with similar biocompatibility as the widespread used poly(2-hydroxyethyl methacrylate). Poly(2-hydroxypropyl acrylate) (PHPA) is a less frequently studied polymer that exhibits thermoresponsive behavior in water. Therefore, copolymers of HEA and HPA are interesting thermoresponsive

Continuous Flow Manufacturing for Monomer Synthesis

The manufacture of monomers for use in ophthalmic applications is driven by the need for higher purity, improved reliability of manufacturing supply, but ultimately by the need for the increased comfort, convenience, and safety of contact lens wearers. Daily wear contact lenses have the potential to fill this need for many customers; however, their widespread use is constrained by higher costs compared to weekly- or monthly-based lenses. New approaches that improve cost structure and result in higher quality raw materials are needed to help make contact lenses more affordable and accelerate growth of the contact lens market.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
