Abstract
We studied permeation behavior for blended or laminated membrane of polydimethylsiloxane (PDMS), polyarylate (PAR), poly (4-methylpentene-1) (PMP) and 1, 2-polybutadiene (1, 2-PB).
As a result shows, in blended system, separation factor of PAR /1, 2-PB system is a value of 4.80, and laminated system of PAR /1, 2-PB system is 5.51.
In the case of laminated membranes, PDMS or 1, 2-PB laminating on the high strength film such as PAR and PMP, obtain significantly excellent separation membranes. These are because of progressing oxygen affinity of PDMS or 1, 2-PB on laminating film.
