Preparation and properties of blends of ion-containing polyurethane with polyvinylpyrrolidone

Binary blends of linear polymers, segmented polyurethane [derived from oligooxytetramethylene glycol (MW 1000), toluene diisocyanate (65 : 35 isomer mixture), and magnesium p-hydroxybenzoate] and poly-N-vinylpyrrolidone (MW 10000), were prepared and studied.
