Hydrophilic membrane comprises a synthetic polymer and an additive which is a copolymer of vinylpyrrolidone (I) and a vinylimidazole compound (II). An Independent claim is also included for production of the membrane which comprises preparing a solution containing the synthetic polymer, forming the solution into a membrane, precipitating the polymer by heat or with a non-solvent, and washing and drying the membrane and optionally treating it with a wetting agent. The additive is added to the polymer solution before or after forming the membrane. |
