Novel homo bis-maleimide compounds containing sulfonate linkages are made by reacting an aromatic disulfonyl halide with m- or p-hydroxy phenyl maleimide and have the following formula: <IMAGE> +TR <IMAGE> Similarly, co-bis-maleimides are made by reaching an aromatic disulfonyl halide, aromatic dihydroxy compound and m or p hydroxy phenyl maleimide having the structural formula: <IMAGE> +TR <IMAGE> Herein R and R' are the same or different and are divalent radicals selected from the group consisting of meta arylene, para arylene, naphthalene and radicals of the formula A-A and A-Z-A wherein A is selected from the group consisting of meta arylene, para arylene and naphthalene and Z is selected from the group consisting of meta arylene, para arylene, naphthalene, carbonyl, sulfone, sulfide, sulfonyl, sulfonate, sulfoxide, ether, methylene, isopropyl, oxygen, alkyl, -CH=CH- and -C 3BOND C- and R1, R2, R3 and R4 are the same or different and are selected from the group consisting of hydrogen, an alkyl group having from 1 to about 4 carbon atoms and a halogen.
