Abstract

Abstract Novel homogeneous, transparent, polymer alloy blends were prepared comprising various ratios of aminopolysiloxane and bromoalkylated polyphenylene oxide derivatives or bromoalkylated methylphosphorylated polyphenylene oxide derivatives. Membranes cast from solvent solutions of the homogeneous, transparent, polymer alloy blends were also transparent and homogeneous and useful as semipermeable membranes for gas separation.
