Study of amphiphilic properties of amine- and oligo(ethylene glycol)-containing (meth)acrylic monomers

Abstract

The two-dimensional classification was applied to the estimation of hydrophilic–hydrophobic properties of four amine-containing (meth)acrylic monomers, 2-hydroxyethyl methacrylate, and four oligo(ethylene glycol) methacrylates of various degrees of the ethoxylation. For the monomers, the standard free energy of partition between water and organic phase and standard free energy of adsorption of monomers at the interface were determined in hexane/water systems. Based on the standard free energy of partition and standard free energy of adsorption amphiphilic properties of the monomers were evaluated in terms of the two-dimensional diagram. The monomers were divided into three groups with respect to the position of the monomers in the diagram. These positions are connected with the nature of the substances. The classification allows estimating of monomers partition between interfaces or bulk phases in systems with developed interfaces.
