Description

N, N′-Bismaleimido-3, 3′-diphenylalkylphosphine oxide (I) was prepared from bis (3-aminophenyl) -alkylphosphine oxide and maleic anhydride. I and aromatic diamines were used for the synthesis of polysuccinimide-amines containing phosphorus atoms in the main chain. The conditions of the polyaddition and the properties of the resulting polymers were investigated. The polymers were obtained in about 70% yield except in the case of using 4, 4′-diaminodiphenyl sulfone as aromatic diamine. The reduced viscosities of the polymers measured at a concentration of 0.2g/dl in DMA at 30°C were 0.16-0.34. Most of the polymers were soluble in dipolar aprotic solvents, m-cresol, and concd. H2SO4. The reduced viscosity of the polymer in concd. H2SO4 decreased gradually. The phosphorus-containing polysuccinimide-amines had poor thermal stability in comparison with the polyimides having aromatic imide rings such as phosphorus-containing polyamide-imides and polyester-imides. The polymers were self-extinguished immediately when a flame was removed.
