Obtaining Peculiarities and Properties of Polyvinylpyrrolidone Copolymers with Hydrophobic Vinyl Monomers

Abstract

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.
