ABSTRACT:
Chlorine-containing polymer containing (a) at least one compound of the formula I ##STR1## in which R.sup.1 is hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.5 -C.sub.6 -cycloalkyl, phenyl or phenyl which is substituted by C.sub.1 -C.sub.4 -alkyl or halogen, n is 1 or 2 and, if n is 1, R is C.sub.1 -C.sub.20 -alkyl, C.sub.1 -C.sub.20 -alkyl which is substituted by --OH or --SH, C.sub.2 -C.sub.20 -alkyl which is interrupted by ##STR2## phenyl, phenyl which is substituted by C.sub.1 -C.sub.4 -alkyl, benzyl, benzyl which is substituted by C.sub.1 -C.sub.4 -alkyl, C.sub.5 -C.sub.6 -cycloalkyl or --NR.sup.2 R.sup.3 in which R.sup.2 and R.sup.3 are identical or different and are as defined for R.sup.1, and, if n is 2, R is a direct bond, C.sub.1 -C.sub.10 -alkylene, C.sub.1 -C.sub.10 -alkylene which is substituted by phenyl, benzyl, --OH, C.sub.1 14 C.sub.4 -alkoxy, C.sub.1 -C.sub.20 -acyloxy, phenylsulfonyl or C.sub.1 -C.sub.4 -alkylsulfonyl or C.sub.2 -C.sub.10 -alkylene which is interrupted by ##STR3## in which R.sup.4 is hydrogen, C.sub.1 -C.sub.4 -alkyl, phenyl, benzyl, naphthyl, cyclohexyl or C.sub.1 -C.sub.20 -acyl, or R is also C.sub.2 -C.sub.10 -alkylidene, phenylene, benzylene or xylylene, and (b) at least one organotin compound and/or lead compound and/or organic antimony compound.
