Interfacial and Solution Polycondensation of Phosphorus Oxychloride with Diamines

Organophosphorus polymers were prepared by the interfacial and the solution polycondensation of phosphorus oxychloride with aliphatic and aromatic diamines. From the results of IR spectrum and elementary analysis it was deduced that the obtained polymers were linear polymers. From the solution viscosity measurement it was deduced that the polymerization degree were low. The reaction conditions in the interfacial polycondensation with hexamethylene diamine (HMD) were investigated.
