The invention relates to stabilizer systems, containing at least: a) a perchlorate salt; b) at least one or more compounds from the group consisting of carbamides, indole derivatives and enamines of formula (I), wherein n=1 or 2 and X=O or NR<SUP>1</SUP>; n=3-6 and X=O; R<SUP>1</SUP>=H, C<SUB>1</SUB>-C<SUB>4</SUB>-alkyl, C<SUB>2</SUB>-C<SUB>6</SUB>-alkenyl, C<SUB>6</SUB>-C<SUB>10</SUB>-aryl, C<SUB>7</SUB>-C<SUB>18</SUB>-alkaryl or C<SUB>7</SUB>-C<SUB>18</SUB>-aralkyl; R<SUP>2 </SUP>(if n=1)=C<SUB>1</SUB>-C<SUB>22</SUB>-alkyl, C<SUB>2</SUB>-C<SUB>22</SUB>-alkenyl or aryl, preferably phenyl, optionally substituted with up to 3 hydroxy, C<SUB>1</SUB>-C<SUB>4</SUB>-alkoxy or C<SUB>1</SUB>-C<SUB>9</SUB>-alkyl; or R<SUP>2 </SUP>(if n=2-6)=linear or branched C<SUB>1-22</SUB>-alkylene, optionally interrupted by one or more O or S atoms, wherein R<SUP>2 </SUP>(if n=3) can also be a C<SUB>2</SUB>-C<SUB>3</SUB>-alkyl trisubstituted isocyanurate; if X=NH R<SUP>2 </SUP>can also be H. Said stabilizer systems are suitable for stabilizing halogen-containing polymers, more particularly PVC.
