Abstract

See full text

The invention is related to a method for producing overbased zinc soaps. Basic zinc carbonate is reacted with organic carboxylic acids with 6 to 22 C-atoms at temperatures of 100 to 200 °C in the absence of organic solvents and the reaction water that is produced is continually distilled off. The resulting compounds are suitable for use as additives for processing plastics and especially for stabilising plastics containing halogen against thermal and/or photochemical decomposition.
