Effect of radiation induced crosslinking on the liquid permeation and separation in some polymeric membranes

Abstract

The effect of radiation induced crosslinking on liquid permeation and selectivity was investigated by pervaporation of polyethylene, poly-4-vinylpyridine and polystyrene membranes. It was found that within the scope of certain radiation dose the radiation induced crosslinking which is relatively sparse has little effect on liquid permeation and separation regardless of the extent of swelling and flexibility of the polymer chain structure.
