Poly2hydroxyethyl
Poly2hydroxyethyl is a polymer derived from 2-hydroxyethyl methacrylate (HEMA). It is a hydrogel, meaning it can absorb and retain significant amounts of water. This property makes it useful in various applications. The chemical structure of poly2hydroxyethyl consists of repeating units of HEMA, which contains a hydroxyl group and a methacrylate ester. The hydroxyl groups are responsible for its hydrophilicity and ability to form hydrogen bonds with water molecules. Poly2hydroxyethyl can be synthesized through various polymerization techniques, including free radical polymerization. The properties of the resulting polymer, such as its swelling ratio and mechanical strength, can be controlled by adjusting polymerization conditions and crosslinking density.
One of the most well-known applications of poly2hydroxyethyl is in the production of soft contact lenses. Its
