Development of Modified Polyolefin Membranes for Reverse Osmosis.

Abstract:

Procedures for the radiation induced grafting of polyethylene film which yield a variety of modified polyethylene membranes have been established. Modification of the polyethylene was accomplished by grafting with acidic monomers such as acrylic and methacrylic acids, basic monomers such as aminoalkyl methacrylates and vinyl-pyridines, and neutral monomers such as hydroxyalkyl methacrylates. Some graft terpolymers were prepared by incorporating relatively hydrophobic monomers such as acrylonitrile, acrylamide, or vinyl acetate into the grafting solution along with acrylic acid. Crosslinking during grafting was accomplished by use of difunctional monomers in the grafting solution. jg p10
