INTRODUCTION
Nowadays the polymer membranes are increasingly used in various barrier applications. Molecular transport of organic liquids through polymer membranes has been the subject of investigations over the past several years [1-6]. Such studies are necessary due to the production of innumerable polymer membrane of commercial importance [7, 8]. The total amount of liquid sorption in polymeric materials is fundamental for applications such as pharmaceuticals, food packaging, electronic, and medical components. Research studies are focused on three major areas of transport mechanism of polymeric materials. These may be designated as diffusion, sorption, and ...
