Abstract: Metal complexes of zinc, copper, cobalt and nickel and N-.beta.-hydroxyalkylated or .gamma.-aminoalkylated .alpha.-aminocarboxylic acids which are substituted at the .alpha.-carbon atom have excellent heat resistance, in particular a good heat resistance under oxydative influences. These complexes are also soluble in many starting components used for obtaining specific polymers. They are therefore especially suitable for obtaining copolymers which contain metal ions, for example polyesters, polyurethanes and polyamides. The copolymers can be used for manufacturing moulded articles.
