Stabilizer system for chlorinated polymers, especially PVC, comprising at least one coordination-polymeric triethanolamineperchlorato(triflato)metal inner complex comprising the monomer unit of the formula (A)
The stabilizer system may additionally comprise substituted cyanoacetylureas or/and 6-aminouracils or/and 3-aminocrotonic esters or/and hydantoins or/and monomeric or polymeric dihydropyridines or alkaline earth metal hydroxides or/and hydrotalcites or/and dawsonites or/and zeolites or/and glycidyl compounds or/and cyanamides or/and cyanoguanidines or/and melamines. In addition, phosphites or/and sterically hindered amines or/and NOR-HALS compounds may be present.
The present invention relates to oxygen-substituted sterically hindered amines of the formulae I or II: (II), wherein, for example, F

are 2,2,6,6-tetramethyl-1-propoxy-piperidin-4-yl. Compositions comprising compounds of formulae I or II and an organic material, which is susceptible to oxidative, thermal or light-induced degradation, are further disclosed. Optionally, further additives are contained.
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.
