General description

2-Hydroxyethyl methacrylate (HEMA) is biocompatible in nature. Polymeric hydrogel scaffold can be produced by polymerizing HEMA in water.

application

A polymeric hydrogel for drug delivery. Patent has been applied for the development of artificial cornea or KPro, it is composed of pHEMA (polymerized from HEMA) and poly (methyl methacrylate)(PMMA). HEMA may be used as a macromonomer for the synthesis of 2-hydroxyethylmethacrylate-poly(ε-caprolactone) (HEMA-PCL) by coordinated anionic ring opening polymerization (ROP).
