    • A description is given of compositions comprising a chlorine-containing polymer and at least one compound of the general formula I where Y is S or O, and R1 and R2 independently of one another are unsubstituted or C1-C4-alkyl-, C1-C4-alkoxy- and/or hydroxyl-substituted phenyl, phenyl-C1-C4-alkyl which is unsubstituted or substituted on the phenyl ring by C1-C4-alkyl, C1-C5-alkoxy and/or hydroxyl, or are C3-C6-alkenyl, C5-C8-cycloalkyl, or C2-C10-alkyl interrupted by at least 1 oxygen atom, or, if R1 and R2 are different from one another, one of the two radicals can be C2-C12-alkyl and the other can be C2-C12-alkyl or one of the above radicals, or, if R1 and R2 are identical, both can also be C5-C12-alkyl, and, if Y is sulfur, R1 and R2 cannot be octyl.
