A composition comprising a chlorinated polymer and at least one monosubstituted 6-aminouracil of the formula I
- wherein
- R1 or R2 is linear or branched C3-C22-alkyl, unsubstituted or C1-C4-alkyl/alkoxy- and/or hydroxyl-substituted phenyl, unsubstituted or C1-C4-alkyl/alkoxy- and/or hydroxyl-substituted phenyl C1-C4-alkyl, linear or branched C3-C18-alkenyl, C3-C8-cycloalkyl, C3-C10-alkyl interrupted by at least 1 oxygen atom, or C3-C10-hydroxyalkyl or acetoxy/benzoyloxy-C2-C10-alkyl and R1 or R2 is hydrogen, and excluding R1 and R2 simultaneously C2-C4 alkyl.
Monosubstituted 6-aminouracils of the formula II
- wherein
- R1 or R2 is C3-C8-cycloalkyl, C4-C10-hydroxyalkyl or acetoxy/benzoyloxy-C2-C10-alkyl and R1 or R2 is hydrogen.
