ABSTRACT:
A composition containing a) a chlorine-containing polymer, b) at least one Me(II) carboxylate and/or Me(II) phenolate, wherein Me(II) represents Ba, Ca, Mg, Sr or Zn, and c) at least one compound of formula I ##STR1## wherein n is 1, 2, 3, 4 or 6 and, when n is 1, X is C.sub.1 -C.sub.20 alkyl, C.sub.3 -C.sub.20 -alkenyl, C.sub.5 -C.sub.12 cycloalkyl, C.sub.5 -C.sub.12 cycloalkyl substituted by C.sub.1 -C.sub.4 alkyl, phenyl, C.sub.7 -C.sub.9 phenylalkyl, phenyl substituted by from 1 to 3 radicals or C.sub.7 -C.sub.9 phenylalkyl substituted on the phenyl ring by from 1 to 3 radicals, the radicals being selected from the group consisting of C.sub.1 -C.sub.4 alkyl, chlorine, hydroxy, methoxy and ethoxy; when n is 2, X is C.sub.2 -C.sub.12 alkylene, C.sub.2 -C.sub.12 alkylene substituted by phenyl, or C.sub.2 -C.sub.12 alkylene interrupted by oxygen or sulfur atoms; when n is 3, X is, for example, C.sub.3 -C.sub.7 alkanetriyl; when n is 4, X is, for example, C.sub.4 .varies.C.sub.10 alkanetetrayl, and when n is 6, X is a group of formula IV ##STR2## Some of the compounds of formula I are novel.
