Chlorine resistant amides, polyamides, and membranes made from the same |
| 摘要 |
A chlorine resistant polyamide is formed from the reaction product of an amine and an acid chloride monomer wherein both the amine and the acid chloride monomer are modified with electron-withdrawing groups that exhibit sufficient activity to (i) minimize any chlorination on both the amine and acid chloride and (ii) minimize N-chlorination. A membrane is made from the polyamide for use, for example, in a desalination unit. |

1. A chlorine resistant polyamide comprising reaction product of an amine and an acid chloride monomer wherein both the amine and the acid chloride monomer are modified with electron—withdrawing such that exhibit sufficient activity to (i) minimize any chlorination on both the amine and acid chloride and (ii) minimize N-chlorination;
the electron withdrawing groups are selected such that the electron-withdrawing group is provided on both end of the amide bond of the polyamide. |
