In this study, poly carbonate (PC) and poly (ethylene terephthalate) (PET) were reactive melt-blended under two different conditions to produce PC/PET copolymers. For each condition, samples were taken at specified mixing times representative a specific structure of copolymers and each one employed to physically compatibilize a PC/PET blend with a fixed composition. Reactive blending and copoly...

In this work, a mathematical model is established to describe the removal of CO2 from gaseous mixtures including CH4 and CO2 in a polypropylene hollow fiber membrane contactor in the presence of conventional absorbents such as monoethanolamine (MEA), methyldiethanolamine (MDEA), and a blend of them. Modeling was performed in axial and radial directions under the fully-wet condition for counterc...

As considerable advance has recently been made in enhancing the conductivity of anion-exchange membranes, durability become critical requirement development fuel cells. Such properties often develop at expense other. In this work, new amphiphilic semi-interpenetrating networks composed free polysulfone and crosslinked are synthesized for first time. The same nature both polymers makes them high...
