Diffusion-transport Properties of Hydrogel Membranes Based on Copolymers of 2-hydroxyethyl Methacrylate with Polyvinylpyrrolidone

The results of researches of dialysis permeability hydrogel films on the basis of copolymers of 2-hydroxyethyl methacrylate with polyvinylpyrrolidone dependently on their composition and modes of dialysis have been carried out. Possibility of synthesized hydrogels applying as the diffusion dialysis membranes has been confirmed.

Composite Hydrogel Materials of Biomedical Application with Fungibactericidal Properties

The new porous compositions on the basis of hydroxyapatite filled copolymers of methacrylic esters and polyvinylpyrrolidone, which containing silver nanoparticles in the structure, were synthesized. Effect of pores forming agent nature, polyvinylpyrrolidone and hydroxyapatite amount on the composite properties was observed. In the composite structure silver nanoparticles are obtained via silver nitrate reduction by tertiary nitrogen of polyvinylpyrrolidone. The synthesized silver-containing composites possesses bactericidal properties.
