Claim 0:
1. A method of making a gas separation membrane comprising a poly(aryl ether), comprising:
providing a first prepolymer comprising a monomer of a formula (X)x—Ar—(OH)y, wherein Ar comprises at least one aryl or heteroaryl group, X is a halogen or a halogen equivalent, each X is the same or different, and x+y is at least two;
providing a second prepolymer comprising a comonomer of a formula (X)x—Ar′—(OH)y wherein Ar′ comprises at least one aryl or heteroaryl group, X is a halogen or a halogen equivalent, each X is the same or different, and x+y is at least two;
providing a catalyst;
providing a base;
reacting the first prepolymer with the second prepolymer in the presence of the catalyst and the base to provide the poly(aryl ether); and
forming the gas separation membrane.
