The application of ultrasound in the synthesis of polyvinylpyrrolidone copolymers and their (nano)composites

The use of ultrasound in synthesis of polyvinylpyrrolidone copolymers with methacrylic esters as well as in the presence of calcium-containing mineral fillers has been researched. The influence of ultrasound on the polyvinylpyrrolidone destruction is determined. The activating impact of ultrasound on initiation of polymerization is confirmed. The ultrasound application significantly intensifies the process of porous composites obtaining that based on polymer-monomer compositions and calcium-containing mineral fillers including nanosized. The developed (nano)composites can be used in medicine to replace damaged bone tissue.
