Phosphorus compounds are provided which correspond to the formula IN WHICH EACH R is an alkyl, alkenyl or halogenalkyl radical, X and X' each is a methyl group or a hydrogen atom, A is a -CO-, -CS-, -SO2-, -CNH- or -CO-NE-CO- radical, wherein E is a hydrogen atom or a Y-CH2-O- radical and wherein Y is an alkyl radical or a hydrogen atom. The phosphorus compounds are manufactured from the corresponding phosphorus carboxylic acid amides, a diamide and formaldehyde. These compounds optionally together with a curable aminoplast precondensate are useful for flameproofing and creaseproofing of cellulose-containing fiber materials.
