The polymerization of hydroxylapatite compositions of 2-hydroxyethylmethacrylate with polyvinylpyrrolidone in the presence of silver salts was researched, and it was found that silver salts retard the polymerization velocity. The composites as porous blocks, that containing in their structure silver nanoparticles, were synthesized and their antibacterial and antifunginal properties were confirmed.
The regularities of receiving the silver nanoparticles by reaction of silver restoring from salts with polyvinylpyrrolidone without using the conventional restoring agents, including toxic substances, were researched. The influence of silver salt nature, medium, polyvinylpyrrolidone molecular weight on the size of nanoparticles was determined. Досліджено закономірності одержання наночастинок срібла реакцією відновлення його з солей полівінілпіролідоном без використання традиційних відновників, зокрема токсичних.
The polymerization of 2-hydroxyethylmethacrylate compositions with polyvinylpyrrolidone has been investigated in the presence of mineral fillers (hydroxyapatite, montmorillonite and wollastonite). The influence of the nature and amount of mineral filler on polymerization kinetics and composition of copolymers has been determined. In the composite structure silver particles were obtained via silver nitrate reduction by polyvinylpyrrolidone tertiary nitrogen. The synthesized silver-containing composites possess bactericidal properties against E. colі and S. aureus bacteria, in particular.
