Polymerization of hydroxyalkyl(meth)acrylates with polyvinylpyrrolidone has been investigated. Thus highly hydrophilic membranes have been obtained and several properties have been investigated including polymerization rate, viscosity, extinction, water permeability of the membranes, their tensile strength and tensile elongation at break. Parameters characterizing complex formation between monomer and polyvinylpyrrolidone are related to structural parameters of resulting copolymer networks. Effective methods of controlling structures as well as properties of highly hydrophilic membranes have been defined.
