Claim:
A stabilizer mixture for stabilizing chlorine-containing polymers, comprising at least a) one alkanolamine of the following formula (I), and b) one uracil of the following formula (II), wherein, for the alkanolamine of the formula (I) x=1, 2 or 3; y=1, 2, 3, 4, 5 or 6; n=from 1 to 10; R 1 and 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, where this may have OH substitution in the β-position, C 6 -C 10 -aryl, C 7 -C 10 -alkaryl or C 7 -C 10 -aralkyl, or, if x=1, R 1 and R 2 may also, together with the N, form a closed ring having from 4 to 10 members, comprising carbon atoms and, optionally, up to 2 heteroatoms, or if x=2, R 1 may also be C 2 -C 18 -alkylene which, at both β-carbon atoms, may have OH substitution and/or have interruption by one or more O atoms and/or by one or more NR 2 groups, or be dihydroxy-substituted tetrahydrodicyclopentadienylene, dihydroxy-substituted ethylcyclohexanylene, 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 and 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; and for the uracil of the formula (II) R 1 and R 2 , independently of one another, are C 1 -C 24 -alkyl, which may have interruption by —CO 2 — and/or by 1 or more oxygen atoms, and/or may have substitution by one or more OH groups, or are C 3 -C 24 -alkenyl, branched or unbranched, or are C 5 -C 8 -cycloalkyl, unsubstituted or substituted with from 1 to 3 C 1 -C 4 -alkoxy, or C 5 -C 8 -cycloalkyl groups, or with hydroxy groups, or with —C1 atoms, or are C 7 -C 9 -phenylalkyl, unsubstituted or substituted on the phenyl ring with from 1 to 3 C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy, or C 5 -C 8 -cycloalkyl groups, or with hydroxy groups, or with —C1 atoms, and R 1 or R 2 may also be hydrogen, and Y is S or O.
