Polymerization of hydrophobic vinyl monomers in polyvinylpyrrolidone aqueous solutions has been investigated under ultrasonic treatment. The effect of ultrasound on the destruction of water-soluble polymeric matrices has been examined. The obtaining mechanism of block- and grafted copolymers of vinyl monomers with polyvinylpyrrolidone has been proposed. The copolymers have been synthesized as films and their main properties, physico-mechanical and sorption-diffusive, in particular, have been investigated.
