  The stabilizer system for chlorine-containing polymers, in particular PVC, comprises at least one linear or cyclic acylureide (A-1) and/or a polyaminocrotonic ester (A-2) and a polyepoxypropyl alcohol ether (B-1) and/or a cyanamide (derivative) (B-2). The stabilizer system may additionally comprise a sterically hindered amine (D) or a tertiary ethanolamine (E) and/or a perchlorate (C-1), perfluoroalkanesulfonate (C-2) and/or sulfate ester (C-3) salt. A typical example is a combination of N,N′-dimethyl-6-iminobarbituric acid as component (A-1), trisepoxypropylglycerol as component (B-1) or dicyandiamide as component (B-2). This combination additionally comprises sodium or potassium perchlorate as component (C-1). Further variants of the invention are the preparation of the stabilizer system, polymer compositions comprising the stabilizer system and utility articles thereof, such as window profiles or wire sheaths.
