In connexion with studies of cyclic polymerisation the allyl derivatives of ethylenediamine and diethylenetriamine have been prepared, and the new compounds have been characterised. The mixture of triamines obtained by direct allylation of diethylenetriamine has been separated by ion-exchange chromatography. The order of elution agrees with the calculated basic strengths of the compounds, and their gas-chromatographic retention ...
