PVI\/PVP is a polyvinylimidazole and polyvinylpyrrolidone adsorbent cross-linked copolymer. The polymer is insoluble and slightly hygroscopic. It has a number of functional imidazole groups which connect selectively and scavenge various metals removing it from wine,mainly copper (Cu), iron (Fe), lead (Pb), cadmium (Cd) and aluminium (Al). The removal of metals was more effective when PVi\/PVP was applied to the wine than to the must. The removal of Fe and Pb was more

Physicochemical propertiesWhite or white-like powder, almost insoluble in all current solvents, so molecular weight cannot be measured;Product standardComply with CP2020,USP43,EP10.0 standards Adsorbent copolymers of PVI\/PVP are insoluble and slightly-hygroscopic powders. They are manufactured by “popcorn” polymerization of N-vinylimidazole (CAS no. 1072-63-5,) and N-vinyl-2-pyrrolidone (CAS no. 88-12-0,), with a ratio of 9:1.
