| 摘要 |
<p>Microporous filtration membranes are provided which are useful for absorbing or adsorbing cationic atoms, molecules or particles from liquids or gases. The invention also concerns novel strongly acidic copolymer solutions capable of crosslinking, and a process for preparing such solutions and making strongly acidic or anionic charge modified microporous filtration membranes therefrom. The copolymer of the solutions is synthesized from 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) and either N-(isobutoxymethyl)acrylamide (IBMA) or 2-hydroxyethyl methacrylate (HEMA).</p> |
