The present invention relates to a stabilizing agent for polymers or copolymers which is a copolymer of ethylene or propylene (A) and a vinyl compound (B) having the formula: wherein X is O, NH or NR<SUB>5</SUB>; R<SUB>1</SUB>, R<SUB>2 </SUB>and R<SUB>3 </SUB>are each independently H, C<SUB>1</SUB>-C<SUB>8 </SUB>alkyl, C<SUB>1</SUB>-C<SUB>8 </SUB>substituted aryl; R<SUB>4 </SUB>is H, C<SUB>1</SUB>-C<SUB>8 </SUB>alkyl, C<SUB>6</SUB>-C<SUB>12 </SUB>cycloalkyl, C<SUB>1</SUB>-C<SUB>10 </SUB>acyl, C<SUB>1</SUB>-C<SUB>10 </SUB>acyloxy or C<SUB>1</SUB>-C<SUB>8 </SUB>alkyl ether; R<SUB>5 </SUB>is C<SUB>1</SUB>-C<SUB>8 </SUB>alkyl and wherein the copolymer has at least 1 mol % (B) and has an MFR<SUB>2 </SUB>of 1-1000 g/10 min. |
