Beschreibung
Zusammenfassung:	1306996 Di-carboxylic acid amides CIBAGEIGY AG 27 April 1970 [28 April 1969] 20160/70 Heading C2C [Also in Divisions C3 and C5] The invention comprises compounds of the formula wherein Y 1 represents a C 3 or C 4 branched alkyl radical, Z 1 represents H or a C 3 or C 4 branched alkyl radical, and n represents an integer from 11 to 16. They may be obtained by reacting a compound of the formula with a compound of the formula wherein A represents OH, halogen or OR wherein R is lower alkyl, in an inert solvent, or in the melt, optionally using a catalyst for splitting off water or, when using an acid halide, employing an acid acceptor, at a temperature from 20 to 250 C. An example is given for the production of the compounds. They are useful as antioxidants for polymers.
