▎ 摘　　要

NOVELTY - A membrane comprises a support layer, and a selective polymer layer arranged on the support layer. The selective polymer layer comprises a selective polymer matrix comprising hydrophilic polymer and an aminosilane cross-linking agent. USE - Membrane e.g. gas permeable membrane used for separating gas such as carbon dioxide, hydrogen sulfide and hydrogen chloride (all claimed). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) separation of gas (G1) from a feed gas stream, which involves contacting a membrane with the feed gas stream comprising gas (G1) under conditions effective to afford transmembrane permeation of the gas (G1); and (2) manufacture of membrane, which involves depositing a selective polymer layer on a support layer.
