Title: POLYMER BLENDED MEMBRANES FOR SOUR GAS SEPARATION
Abstract:
A method of separating gas and a method of making a gas separation membrane. The method of separating gas includes flowing a gas stream through a membrane, in which the membrane comprises a crosslinked mixture of a poly(ether-b- amide) copolymer and an acrylate-terminated poly(ethylene glycol) according to formula (I) or formula (II); and separating the gas stream via the membrane. In formulas (I) and (II), each n is of from 2 to 30; and each R is independently ―H or ―CH3
