The regularities of obtaining of osteoplastic porous composites based on 2-hydroxyethyl methacrylate with polyvinylpyrrolidone copolymers in the presence of mineral fillers (hydroxyapatite, montmorillonite and wollastonite) under ultrasound are researched. The influence of ultrasound, nature and amount of inorganic filler on the polymerization rate, copolymers composition and composites porosity has been determined. It was found that homopolymerization of 2-hydroxyethyl methacrylate without filler under ultrasound action does not occur in experiment conditions.
Usually, in chemical industry the energy of ultrasound is being used to intensify technological processes. However, the complexity of the mechanism of ultrasound action makes it difficult to create a single common theory that could explain its influence on the chemical reactions. Therefore, in each particular case wide-ranging studies of the influence of ultrasound on the chemical reaction, as well as on the structure and properties of the synthesized substances and materials are required.
