2-hydroxyethyl methacrylate

Рolymerization regularities, structure and properties of polyvinylpyrrolidone copolymers obtained in a permanent magnetic field

The effect of a constant magnetic field on the polymerization of 2-hydroxyethyl methacrylate in the presence of a polyvinylpyrrolidone has been studied. The regularities of copolymer formation under different synthesis conditions, particularly depending on the magnetic field intensity, were identified. It has been shown that the magnetic field activates the complexation between the monomer and the polymer matrix, increasing the polymerization rate and the degree of structural order in the copolymers.

Hydrogels in Biomedicine: Granular Controlled Release Systems Based on 2-Hydroxyethyl Methacrylate Copolymers. A Review

The article analyzes and summarizes the latest achievements in the field of polymer systems for controlled release devices based on hydrogel materials. Possible directions of drug delivery are presented, including the use of granular hydrogels, which work on the principle of drug sorption − release in the body.

Selective Removal of Mercury(II) Using Hydrogels Prepared by Gamma Radiation

To selectively remove mercury(II), 2-hydroxyethyl methacrylate (HM) and 2-hydroxyethyl methacrylate/acrylamide (HM/ACR) hydrogels were synthesized using radiation. These hydrogels were used in swelling, diffusion, and binding studies. Swelling parameters for HM/ACR−Hg2+ system are higher than those of HM−Hg2+ systems. Binding of Hg2+ has been observed to be C-type for HM and L-type for HM/ACR hydrogels. Binding parameters were calculated using Freundlich, Langmuir and Henry models.

The Ultrasonic Effect on Obtaining and Properties of Osteoplastic Porous Composites

The grafted copolymerization of 2-hydroxyethyl methacrylate to polyvinylpyrrolidone in the presence of mineral fillers (hydroxyapatite, montmorillonite and wollastonite) under ultrasound has been investigated. The effect of ultrasound, nature and amount of mineral filler on the polymerization rate and composition of copolymers has been determined. Ultrasound substantially intensifies the polymerization process and actively affects the formation of the copolymer composition. Under its action, a porous structure of composites is formed, even without adding special foaming agents.

Possibility of Using Embolizing Preparation Derived from Poly(2-Hydroxyethyl Methacrylate) (Poly-HEMA) for Chemoemobolization

The principal opportunity of uptaking weakly crosslinked hydrogel emboli is shown by Doxorubicin at different temperatures. The optimal process time is 1.5–2.5 h. It is revealed that Doxorubicin is capable to diffuse from a polymeric matrix, having targeted medical effect on surrounding tissue and reducing side impacts on other organs.
