Abstract
Official abstract text for this publication.
A polymeric membrane includes an active layer on a support. The active layer includes at least two chemically distinct crosslinked, polyamide films, and the films are crosslinked with each other at an interface.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of making a composite membrane, comprising: (i) applying a chemical mixture (A) to a support membrane to form a treated support membrane, wherein the chemical mixture (A) comprises an aqueous solution of a monomeric polyamine reactant represented by Formula 1: R(NH 2 ) z Formula 1 wherein R represents an organic group selected from aliphatic, alicyclic, aromatic, heterocyclic groups and combinations thereof, and z represents an inte…
