ABSTRACT:
The present invention is a class of polymeric membranes formed from aromatic polyarylates derived from dicarboxylic acid chlorides and cardo bisphenols having halo substituents on all portions ortho to the hydroxy functions. These polyarylate membranes exhibit high gas permselectivities and are useful in various gas separation applications.
