(Hydroxyethyl)methacrylate
- (Hydroxyethyl)methacrylate
Hydroxyethylmethacrylate or HEMA is the monomer that is used to make the polymer PolyHydroxyethylmethacrylate. The polymer is hydrophilic; therefore, when the polymer is subjected to water it will swell. Depending on the physical and chemical structure of the polymer, it is capable of absorbing from 10 to 600% water relative to the dry weight. Because of this property, it was one of the first materials to be successfully used in the manufacture of flexible contact lenses [Blasco, Joe; Kehoe, Vincent J-R; "The professional make-up artist : motion pictures, television, print, theatre"; ISBN 0977158004; LCC# PN2068.B53 2005]
