The present invention provides a monomer composition comprising an aromatic halosulfonyl isocyanate having structure I (Formule I) wherein "m" is an integer from 2 to 5; "n" is an integer from 1 to 5; Ar is a C3-C40 aromatic radical which is free of aliphatic carbon-hydrogen bonds; and X is halogen. The monomer compositions comprising aromatic halosulfonyl isocyanate I are useful in the preparation of polymeric materials useful as membranes which are also provided by the present invention.
