General description

2-Hydroxyethyl methacrylate (HEMA) is biocompatible in nature. Polymeric hydrogel scaffold can be produced by polymerizing HEMA in water.[58]

Application

A polymeric hydrogel for drug delivery.[79] 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). [60] 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). [59]
