POLY(2-HYDROXYETHYL METHACRYLATE) Usage And Synthesis

Uses

Poly(2-hydroxyethyl methacrylate) has been used:

• as a nonadhesive substrate in the preparation of single cell suspensions
• to implant into mice cornea for corneal micropocket assay
• to coat the well plates for sphere assay using adipose-derived mesenchymal stem cells

Uses

pHEMA scaffolds are used in tissue engineering. It can be used in hydrogels for biomedical applications, as sorbents for metal ions.pHEMA has been used in applications such as soft contact lenses, in drug delivery systems, and in kidney dialysis membranes.Nanoparticles of pHEMA may be employed as a carrier for controlled delivery of anticancer and antitumor drugs.

Definition

ChEBI: An acrylate macromolecule, composed of repeating 2-hydroxyethyl 2-methylpropanoate units.

General Description

Solid Poly(2-hydroxyethyl methacrylate) (pHEMA) is brittle, while pHEMA hydrogel is a soft material. Glass transition temperature for pHEMA hydrogels is reduced by increasing a content of water in the matrix. Macromolecular properties in pHEMA are characterized by non-covalent interactions of hydrogen-bonds among the polymer chains as well as the hydrated water molecules. The presence of polar groups of hydroxyl and carboxyl on each repeat unit makes this polymer compatible with water. The hydrophobic a-methyl groups of the backbone convey hydrolytic stability to the polymer and enhance mechanical strength of the polymer matrix.

Biochem/physiol Actions

Poly(2-hydroxyethyl methacrylate) is an acrylic compound and has dental usage. It is mainly used to inhibit cell adhesion to growth surfaces in culture vessels.

Solubility in organics

DMF, methanol, methyl cellosolve
