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 aminecontaining (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.

Selective solvent conditions influence sequence development and supramolecular assembly in step-growth copolymerization

“…The resulting non-standard reaction kinetics can be further altered by the alignment of nascent oligomers with longer persistence lengths. 15 This type of local concentration enrichment has previously been reported in both experimental and computational observations of the ''bootstrap'' effect, 13,[16][17][18][19][20][21] in which an increase in the local availability of one monomer type shifts the relative kinetics of comonomer pairs during a reaction. Analogous behavior occurs in polymerization induced self-assembly (PISA), a widely studied synthetic approach in which a controlled radical polymerization drives self-assembly among nascent oligomers This journal is © The Royal Society of Chemistry 2022 consisting of a growing block of one type of monomer attached to a pre-formed oligomer of a different type.…”

Amphiphilic properties of alkoxyoligoethyleneglycol methacrylates and copolymers based on them

“…Одним из часто применяемых вариантов является определение ГЛБ с помощью измерения коэффициента распределения вещества в смесях неполярного растворителя (обычно -углеводорода) и воды  например, используются системы октанол-вода, гептан-вода, гексан-вода и др. [5]. Мы выбрали для АОЭГМ именно такой вариант определения ГЛБ, как наиболее приближенный к характеристикам растворимости в воде полимеров на основе этих макромономеров.…”

A novel approach to prepare large-scale and narrow-dispersed latex particles by emulsion polymerization based on particle coagulation mechanism

“…[1][2][3][4][5][6][7] However, determining the relationship between particle coagulation and particle size distribution of final latex particles is still a matter of debate, for instance, Ishii et al [8] considered that a steady growth without the aggregation of particles was necessary for preparing monodisperse polymer particles; In contrast, Telford et al [9] considered that the monodisperse polymer particles could be obtained in the presence of particle coagulation.…”
