Description

Hydroxyethylmethacrylate or HEMA is the monomer that is used to make the polymer polyhydroxyethylmethacrylate. The polymer is hydrophobic; however, when the polymer is subjected to water it will swell due to the molecule's hydrophilic pendant group. 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

  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

2-Hydroxyethyl methacrylate, present at 100 mg/l, reached 92-100% of its theoretical BOD in 2 weeks using an activated sludge inoculum and the Japanese MITI test(1).

12.3 Bioaccumulative potential

An estimated BCF of 1.3 was calculated for 2-hydroxyethyl methacrylate(SRC), using a log Kow of 0.47(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is low.

12.4 Mobility in soil

The Koc of 2-hydroxyethyl methacrylate is estimated as approximately 43(SRC), using a log Kow of 0.47(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 2-hydroxyethyl methacrylate is expected to have very high mobility in soil.
