PRODUCTION OF ISOCYANATE-SUBSTITUTED ISOPHTHALOYL CHLORIDE |
| 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 polyamideurea formed in situ by reaction of isocyanate-substituted acyl chloride and a diamine-treated microporous substrate. |
