Reverse osmosis membranes of polyamideurethane |
| 摘要 |
The present invention is directed to an improved reverse osmosis membrane that shows surprisingly improved solute rejection and permeation properties. The membrane includes a separating layer of a polyamideurethane formed in situ by reaction of a haloformyloxy-substituted acyl haldide with a diamine-treated substrate.
