Abstract (en)

[origin: DE19511016A1] Described is an agent for the stabilization of halogen-containing plastics against thermal or photochemical degradation, the agent containing cationic sheet-structure compounds of the general formula (I) [M<(II)>xAl(OH)y](A<n->)z.mH2O. The agent is characterized in that it is produced by reacting an aqueous mixture of at least one source of bivalent metal ions (M<(II)>), at least one source of anions (A<n->) and crystalline aluminium hydroxide with 1 to 20 mole %, relative to the aluminium hydroxide, of alkali-metal hydroxide for between 10 and 240 minutes at a temperature between 100 and 240 DEG C and, without separating the solids from the aqueous phase, drying to a powder.
