ABSTRACT:
The process of producing a reverse osmosis membrane by the steps of preparing a liquid mixture of N-vinyl pyrrolidone, maleic anhydride and maleimide, wetting a porous membrane with the mixture and irradiating the wetted membrane with laser energy with energy sufficient to polymerize the mixture to form a terpolymer of N-vinyl pyrrolidone, maleic anhydride and maleimide on the membrane.
