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.
含有磺酸酯键的新型双马来酰亚胺化合物是通过将芳香二磺酰卤化物与间位或对位羟基苯基马来酰亚胺反应制得的,其具有以下公式:##STR1##。同样,共双马来酰亚胺是通过将芳香二磺酰卤化物、芳香二羟基化合物以及间位或对位羟基苯基马来酰亚胺反应制得的,其具有结构公式:##STR2##。其中R和R'相同或不同,是二价基团,选自包括间位芳香族、对位芳香族、萘基以及公式A--A和A--Z--A的基团,其中A选自包括间位芳香族、对位芳香族和萘基的组,Z选自包括间位芳香族、对位芳香族、萘基、羰基、磺酰基、硫醚、硫酰基、磺酸酯、亚砜、醚、亚甲基、异丙基、氧、烷基、--CH.dbd.CH--和--C.tbd.C--的组,且R.sub.1、R.sub.2、R.sub.3和R.sub.4相同或不同,选自包括氢、具有大约1到4个碳原子的烷基组以及卤素的组。
