In gas separation, the trade off limitations of polymeric membranes and economical consideration of
inorganic membranes motivated the researchers to search for alternative approaches. Membranes with high
selectivity and high permeability are required. Different modifications are in practice to improve the performance of
membranes like mixed matrix, cross linking, grafting, polymer blending, making composite or hybrid membrane. It
will be possible to develop polymeric blend membrane for separating high pressure gas streams at their processing
pressure. This advantage could offer cost savings that may provide a new incentive for polymeric blend membranes.
This result opens a new tool for studying gas separation by polymeric blend membranes. In this context blending of
glassy and rubbery polymer that is Polysulfone and Polyvinyl acetate in dimethyl acetamide solvent, flat sheet
membranes were developed with desirable properties. Membranes were synthesized with different blending ratios
and the developed membranes were characterized by Fourier Transformed Infra-Red Spectroscopy (FTIR), Thermal
Gravimetric Analysis (TGA), Field Emission Scanning Electron Microscopy (FESEM) and Gas Permeability to
study the effect of blend ratio on different properties.
