Unter Resten mit sterisch gehinderten Aminogruppen sind im allgemeinen alle cyklischen Reste zu verstehen, die eine Gruppierung der Formel -C(Alkyl)₂-NH-C(Alkyl)₂- aufweisen, wobei das Wasserstoffatom durch einen Alkyl- oder Acylrest substituiert sein kann und die Alkylreste 1 bis 4 Kohlenstoffatome enthalten.Among radicals with sterically hindered amino groups are in general to understand all cyclic residues that are a grouping of the formula -C (alkyl) ₂-NH-C (alkyl) ₂-, wherein the hydrogen atom by a Alkyl or acyl radical may be substituted and the alkyl radicals 1 to 4 Contain carbon atoms.
Vorzugsweise enthalten die neuen synthetischen Polyamide (bzw. oligomeren Amide) pro Molekül etwa 5 bis 200, vorzugsweise 10 bis 50 sterisch gehinderte Aminogruppen, das heißt, daß die Zahl der sterisch gehinderten Aminogruppen durch Kontrolle des Polymerisationsgrades (Kettenabbruch) festgelegt wird, bzw. daß bei der Herstellung pro 10 Mol Dicarbonsäure, bzw. Diamin (bzw. pro 20 Mol Lactam) etwa 0,1 bis 5 Mol einer polykondensierbaren Verbindung mit einer oder zwei sterisch gehinderten Aminogruppen eingesetzt werden. Dabei muß natürlich die eingesetzte Menge Diamin (ohne sterisch gehindertes Amin) entsprechend reduziert werden, bzw. ganz wegfallen, wenn das sterisch gehinderte Amin Bestandteil eines Diamins ist, bzw. muß die Menge Dicarbonsäure entsprechend (wenn nötig auf Null) reduziert werden, wenn das sterisch gehinderte Amin Bestandteil einer Dicarbonsäureverbindung ist.

Of course, the amount used Diamine (without sterically hindered amine) can be reduced accordingly, or completely eliminated if the hindered amine is part of a Diamins is, or must the amount of dicarboxylic acid accordingly (if necessary to zero) when the hindered amine is an ingredient a dicarboxylic acid compound.
