ABSTRACT:
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: ##STR1## 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: ##STR2## 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.dbd.CH-- and --C.tbd.C-- and R.sub.1, R.sub.2, R.sub.3 and R.sub.4 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.
