Patent ID: 7077981

Claim:
A stabilizer system for stabilizing halogen-containing polymers, wherein said system comprises: a) a perchlorate salt; and b) at least one enamine of the formula (I) wherein: n is an integer of from 1 to 6; if n is 1 or 2, then X is O or NR 1 , if n is 3 to 6, then X is O; R 1 is selected from the group consisting of H, C 1 –C 4 -alkyl, C 2 –C 6 -alkenyl, C 6 –C 10 -aryl, C 7 –C 18 -alkaryl, and C 7 –C 18 -aralkyl; if n is 1, then R 2 is selected from the group consisting of C 1 –C 22 -alkyl, C 2 –C 22 -alkenyl, and aryl, each of which may be substituted with up to 3 hydroxyl, C 1 –C 4 -alkoxy or C 1 –C 9 -alkyl groups; or if n is from 2 to 6, then R 2 is a linear or branched C 1-22 -alkylene, which may be interrupted by one or more O atoms or S atoms, provided that if n is 3, then R 2 may also be a C 2 –C 3 -alkyl-trisubstituted isocyanurate; and provided that if X is NH, then R 2 may also be hydrogen.
