✦ Synopsis

New phosphorus-, nitrogen-and difuryl-containing monomers have been prepared via the addition of dialkyl phosphites (dimethyl, diethyl and diisopropyl) to Schiff bases from furfural and the following amines 4,4'-diaminodiphenyl ether, 4,4'-diaminodiphenylmethane and p-phenylene diamine. The structures of the monomers were determined by i.r. and tH-NMR spectroscopy. It was found that the phosphorus-, nitrogen-and difuryl-containing compounds react with isocyanates and that they homopolymerize and co-polymerize with difurfurylidene acetone.

## Abstract Phosphoramide containing an active vinyl group (P‐III) was prepared. Its structure was confirmed by elemental analysis and Fourier transform infrared, nuclear magnetic resonance, and mass spectroscopy. P‐III was evaluated as a fire‐retardant finishing agent for cotton fabrics. It was ap
