A series of novel metal-containing bismaleimides monomers BMI(M) (M Å Ca, Sr, Ba, Pb, Co, Ni) were prepared by reacting maleic anhydride with diaminodiphenyl carboxylate to form bismaleamic acid precursors, and subsequently by imidizing them chemically or thermally to form bismaleimides. The samples

Some 50 metal-containing polyimides with the metallic elements (Mg, Ca, Sr, Ba, Pb, Co, Ni) in the main chain were prepared first by reacting pyromellitic dianhydride (PMDA) with the mixture of divalent metal salts of p-aminobenzoic acid [ABA(M)] and 4, 4'-diaminodiphenylmethane (MDA) to form polyam
