Abstract
New phosphorus containing oligomeric compounds of general formula ((NRCH2CH ROP)-C-1-O-2(O)R)(n), analogous to polypeptides, were isolated and characte rised. These are stable intermediaries in the acid catalysed imide-amide re arrangement of cyclic phosphorimidates through a ring-opening polymerisatio n, revealing an intermolecular two step mechanism for this rearrangement.
