## Abstract Waterβswollen hydrogel (WSH) membranes for gas separation were prepared by the dipβcoating of asymmetric porous polyetherimide (PEI) membrane supports with poly(vinyl alcohol) (PVA)βglutaraldehyde (GA), followed by the crosslinking of the active layer by a solution method. Crosslinked P
The permeability to water and the average pore radius of transparent hydrogels from glyceryl methacrylate (GMA), 2-hydroxyethyl methacrylate ( m M A ) , propylene glycol monoacrylate (PGMA), and a polyelectrolyte complex were determined. The transport process was found to be a predominantly viscous
