Abstract: The present invention provides hydrophilic surface modifying macromolecules (H-phil SMM) and H-phil SMM and blended membranes produced incorporating the hydrophilic surface modifying macromolecules. The membranes include a hydrophilic base polymer, and the hydrophilic surface modifying macromolecules (H-phil SMM) which impart surface hydrophilic properties to the membrane. The membranes produced with the surface modifying macromolecules give polymer membranes useful in the separation of water from a solution containing volatile organic compounds and water.
