摘要:
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 NR1; n=3–6 and X=O; R1=H, C1–C4-alkyl, C2–C6-alkenyl, C6–C10-aryl, C7–C18-alkaryl or C7–C18-aralkyl; R2 (if n=1)=C1–C22-alkyl, C2–C22-alkenyl or aryl, preferably phenyl, optionally substituted with up to 3 hydroxy, C1–C4-alkoxy or C1–C9-alkyl; or R2 (if n=2–6)=linear or branched C1-22-alkylene, optionally interrupted by one or more O or S atoms, wherein R2 (if n=3) can also be a C2–C3-alkyl trisubstituted isocyanurate; if X=NH R2 can also be H. Said stabilizer systems are suitable for stabilizing halogen-containing polymers, more particularly PVC.
