Abstract of the Disclosure Shaped or unshaped synthetic resins having about 0.01-5% by weight of stabilizers where the stabilizers are bisamides of quadratic acids having the general formulas I and/or II as follows: Image I Image II wherein R1, R2, R3, and R4, are identical or different, and represent (A) hydrogen, unsubstituted or substituted alkyl or alkenyl residues of 1-22 carbon atoms, one or more of which can also be substituted by hetero atoms; (B) unsubstituted or substituted cycloalkyl or cycloalkylalkylene residues; (C) unsubstituted or substituted aryl and arylalkylene residues; (D) 3- to 8-membered, unsubstituted or substituted rings which contain one or more hetero atoms and which can optionally be connected to the nitrogen atoms of Formulae I and II by way of alkylene groups; (E) furthermore the groups -NR1R2 and/or -NR3R4 represents 3- to 8- membered, unsubstituted or substituted rings which optionally contain additionalhetero atoms; and (F) respectively R1 and R3 or R2 and R4 represent unbranched or branched, ring-anellated, saturated or unsaturated aliphatic chains which optionally carry functional groups.
