Claim:
A composition comprising a chlorine-containing polymer having dispersed therein a stabilizer mixture comprising: a) at least one perchiorate salt and b) one alkanolamine of the formula (I) where x=1, 2 or 3 y=1, 2, 3, 4, 5 or 6, n=1-10 R 1 , R 2 = independently of one another, H, C 1 -C 22 -alkyl, —[—(CHR 3 a ) y —CHR 3 b —O—] n —H, —[—(CHR 3 a ) y —CHR 3 b —O—] n —CO—R 4 , C 2 -C 20 -alkenyl, C 2 -C 18 -acyl, C 4 -C 8 -cycloalkyl, which may be OH-substituted in the β position, C 6 -C 10 -aryl, C 7 -C 10 -alkaryl or C 7 -C 10 -aralkyl, or when x =1, R 1 and R 2 may additionally combine with the N to form a closed 4-10-membered ring of carbon atoms and optionally up to 2 heteroatoms, or when x=2, R 1 may additionally be C 2 -C 18 -alkylene which may be OH-substituted at both β-carbon atoms and/or may be interrupted by one or more O-atoms and/or one or more NR 2 groups, or dihydroxy-substituted tetrahydrodicyclopentadienylene, dihydroxy-substituted ethylcyclo-hexanylene, dihydroxy-substituted 4,4′-(bisphenol A dipropyl ether)ylene, isophoronylene, dimethylcyclohexanylene, dicyclohexylmethanylene, or 3,3′-dimethyldicyclohexylmethanylene, and if x=3, R 1 may also be trihydroxy-substituted (tri-N-propyl isocyanurate)triyl; R 3 a , R 3 b =independently of one another, C 1 -C 22 -alkyl, C 2 -C 6 -alkenyl, C 6 -C 10 -aryl, H or CH 2 -X-R 5 , where X=O, S, —O—CO— or —CO—O—; R 4 =C 1 -C 18 -alkyl/alkenyl or phenyl, and R 5 =H, C 1 -C 22 -alkyl, C 2 -C 22 -alkenyl or C 6 -C 10 -aryl.
