Abstract 1 Mole of benzenephosphonic diisocyanate reacts with 2 moles monoamines to give the corresponding bis-[ureas]; with 1 mole or 0, 5 mole diamine polyurea compounds are formed. With alcohols bis-[carbamic acid esters] and with diols polyurethanes are obtained. Synthesis, IR-spectra and properties of these compounds are described.
