die bisher erwähnten polyamingemische weisen, bedingt durch ihre herstellung aminogruppen auf, die praktisch nur orthoständig und/oder paraständig zu methylengruppen sind.
the polyamine mixtures mentioned thus far exhibit, by virtue of their method of preparation, amino groups which are virtually only in the ortho and/or para position to methylene groups.

Qualità:
das kriterium "orthoreich" und "orthoarm" oder der ortho-substitutionsgrad erfaßt in diesen polyamingemischen nicht mehr alle isomeren und ist daher sinngemäß anzuwenden, indem anstelle der begriffe "orthoständig" und "paraständig" eine einteilung der isomeren vorgenommen wird in solche mit kleinerem (= ortho) und solche mit größerem (= para) räumlichen abstand der - in der regel an unterschiedlichen sechsringen befindlichen - aminogruppen zur methylenbrücke bzw. der aminogruppen zueinander.
not all the isomers in these polyamine mixtures still fit the criterion of "ortho-rich" and "ortho-poor" or of the degree of ortho-substitution, which should therefore be applied by analogy, by classifying the isomers into those having a smaller (=ortho-) and those having a greater (=para-) spatial distance between the--generally to be found on different six-membered rings--amino groups and the methylene bridge or between the amino groups themselves, in place of the terms "in the ortho position" and "in the para position".
