Abstract EN
Efficacy of photoinitiators such as riboflavin (RF), camphorquinone (CQ), and safranin T (ST) and triethanolamine as a coinitiator has been compared in carrying out the polymerization of 2-hydroxyethyl methacrylate (HEMA) in aqueous and organic solvents.
HEMA solutions were polymerized in the presence of RF, CQ, and ST using a low intensity visible radiation source.
HEMA was assayed by a UV spectrophotometric method during the initial stages of the reactions (i.e., ~5% change).
A comparison of the efficacy of photoinitiators in causing HEMA polymerization showed that RF is more efficient than CQ and ST.
The rate of polymerization is directly related to solvent dielectric constant and inversely related to the solvent viscosity.
RF is the most efficient photoinitiator in the polymerization of HEMA and the highest rate of reaction occurs in aqueous solutions.
A general scheme for the polymerization of HEMA in the presence of photoinitiators is presented.
