Abstract (en)

[origin: WO9946322A1] The invention concerns the use of zinc acetylacetonate comprising at least 4.4 wt.% of water as stabilising agent for halogenated polymers. The invention also concerns a method for preparing monohydrate zinc acetylacetonate which consists in contacting a zinc oxide and/or hydroxide with acetylacetone, in the presence of a solvent; said solvent being used in a quantity ranging between 20 and 200 parts by weight, for 100 parts by weight of acetylacetone.
