Abstract
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; n=3–6 and X=O; R=H, C–C-alkyl, C–C-alkenyl, C–C-aryl, C–C-alkaryl or C–C-aralkyl; R(if n=1)=C–C-alkyl, C–C-alkenyl or aryl, preferably phenyl, optionally substituted with up to 3 hydroxy, C–C-alkoxy or C–C-alkyl; or R(if n=2–6)=linear or branched C-alkylene, optionally interrupted by one or more O or S atoms, wherein R(if n=3) can also be a C–C-alkyl trisubstituted isocyanurate; if X=NH Rcan also be H. Said stabilizer systems are suitable for stabilizing halogen-containing polymers, more particularly PVC.
